How long does it take to charge battery in solar fence charger?

    1. A solar powered electric fence energizer usually contains a battery for energy storage. The solar panel collects the energy from the sun and charges the battery. Lead acid batteries, which are used in solar fence chargers, typically last around 3 years, or around 1,000 days of charging.

Pontiac Montana sv6 2006 electrical or what? Volts keep jump in from 12.3 to 15 while I drive .got stuck on highway 3 times when the voltage hits below 12.1 just swapped the battery...please help

Have your (alternator) Charging system tested ! .This is a computer controlled charging system .
The body control module (BCM) is a class 2 device. It communicates with the powertrain control module (PCM)/engine control module (ECM) and the instrument panel cluster (IPC) for electrical power management (EPM) operation. The BCM determines the output of the generator and sends the information to the PCM/ECM for control of the generator field control circuit. It monitors the generator field duty cycle signal circuit information sent from the PCM/ECM for control of the generator. It monitors a battery current sensor, the battery positive voltage circuit, and estimated battery temperature to determine battery state-of-charge (SOC). The BCM performs idle boost and load management operations.
Powertrain Control Module (PCM)/Engine Control Module (ECM) The PCM/ECM directly controls the generator field control circuit input to the generator. It monitors the generator's generator field duty cycle signal circuit and sends the information to the BCM. The PCM/ECM will override the BCM control of the generator when one of the following conditions is met:
The engine cooling fans are on high speed.

There is a high fuel demand.

The calculated ambient air temperature is less that 0?°C (32?°F).

Generator suddenly wont stay running

take all the load from it

start it does it run??

if it does then the gen is prob aok
your taking too much load when it starts

if this isnt the case

check for fuel flow and also air flow
other than this its an electrical system and detection problem

Have a 1993 ford e350 jamboree that the alternator is overcharging, put new voltage reg. unit on alternator and it seem to fix the problem, but when i went to use it again the charging light came back on...

If you have an engine computer that controls the alternator, you will have to check the wiring from the alt. to the PCM. Also check any fusible links and grounds are often overlooked.
Do you have dual alternators?

SECTION 414-00: Charging System - General Information 2002 E-Series Workshop Manual
DESCRIPTION AND OPERATION Charging System The charging system is a negative ground system consisting of the following:
  • generator
  • integral/internal voltage regulator
  • charging system warning indicator
  • storage battery
  • necessary wiring and cables
The generator is belt-driven by the engine accessory drive system. Refer to wiring diagrams for schematics and locations of the components and wiring.
The battery is a 12 volt direct current source connected in a negative ground system. The battery case is sealed and includes two vent holes to release gases. The battery has three major functions:
  • engine cranking power source
  • voltage stabilizer for the electrical system
  • temporary power when electrical loads exceed the generator output current
The optional dual generator package (7.3L diesel engine only) consists of an upper/lower dual generator system. The upper generator is a 6G 50/110 generator with a 2.49:1 pulley ratio. The lower generator is a 6G 50/110 generator with a 2.32:1 pulley ratio. Thus the upper and lower generators are not interchangeable.
This system is also monitored and controlled by the powertrain control module (PCM). The PCM monitors both the upper and lower generator I circuits to determine both generators' output and set possible fault codes (diagnostic trouble codes [DTCs]). The PCM only controls the lower generator by turning it on or off by opening or closing the lower generator off only when the glow plugs are commanded on by the PCM to avoid possible damage (excessive voltage) to the glow plugs.
Both generators are independent of one another and only control themselves (through their own internal voltage regulator). If one generator fails, the other generator can maintain system performance under light load conditions. Under a heavy load, the PCM should detect a problem, set a DTC and illuminate the warning indicator.
The PCM controls the charging system warning indicator and will command the light on if the PCM detects a problem on the monitored circuits.

Code P0621

P0621 Generator Lamp/L Terminal Circuit Malfunction,,The Engine Control Module (ECM) or Powertrain Control Module (PCM) uses the generator turn on signal circuit to control the load of the generator on the engine. A high side driver in the ECM/PCM applies a voltage to the voltage regulator. This signals the voltage regulator to turn the field circuit ON and OFF. The ECM/PCM monitors the state of the generator turn on signal circuit. The ECM/PCM should detect low voltage on generator turn on signal circuit when the ignition is ON and the engine is OFF, or when the charging system malfunctions. With the engine running, the ECM/PCM should detect high voltage on the generator turn on signal circuit. The ECM/PCM performs Ignition ON and RUN tests to determine the status of the generator turn on signal circuit.

We changed the alternater like four times the battery light wont turn off, we have even check some wire

the plug on the alt will some times go bad usually melting this is normally the cause of this

Check engine light on....cooling fan over speeds. I replaced the fan clutch and still does the samething...a lot of air noise...specially when starting out / accelerating

Check engine light is part of the solution as the code stored may indicate the malfunctioning sensor.The fan overspeed is a computer generated safety backup for electric fan clutch engagement so the engine don't overheat when the coolant temp sensor malfunctions.

1999 Honda Odessey P1259 VTEC System Circuit Fault (Bank 1)

I would first try and reset the Powertrain Control Module since you replaced the alternator. This will clear all the codes and turn off the check engine light. To do this, pull the No. 13 "clock backup" fuse from the passenger kick panel fuse box for 10 seconds then replace.

Now, you should also do the Honda "idle learn procedure". This lets the computer calculate what a no load idle condition is so it can adjust idle speed when the engine or alternator is put under various loads. To do this, make sure all electrical items are turned off. Start the engine and hold it at 3,000 rpm in park or neutral until the radiator fan comes on or until normal operating temp is reached (about 4 minutes). Now let the engine idle for a minimum of 5 minutes with no loads. If the radiator fan comes on during the 5 minutes, the amount of time it runs must be added to the 5 minute period--the goal being a period of at least 5 minutes without any loads on the engine or alternator.

Also check the vacuum line to the evap solenoid. It is on the top of the engine near the intake throttle body.

Alternator problem?

check battery voltage with engine off. should be @ 12.5v
check with engine running at about 1500 rpms. It should be @ 14 volts. If yes, it is ok. I think you are ok.
Please rate higly if htis helps

your system is more sophisticated than Sars can handle.

here's how it works.

The charging system consists of a generator which generates current to supply the vehicle electrical system and maintain the battery in a charged condition.
The generator is driven by the accessory drive belt. For additional information, refer to Section 303-05 . When the engine is started, the generator begins to generate alternating current (AC) which is converted to direct current (DC) internally. The DC current is controlled by the voltage regulator (located on the back of the generator), and then supplied to the battery.
The charging system voltage is controlled by the powertrain control module (PCM). The generator charges the battery and at the same time it supplies all the electrical loads that are required. The battery is more effectively charged with a higher voltage when the battery is cold and a lower voltage when the battery is warm. The PCM is able to adjust the charging voltage according to battery temperature by using a signal from the intake air temperature (IAT) sensor. This means that the voltage setpoint is calculated by the PCM and communicated to the regulator by a communication link.
The PCM simultaneously controls and monitors the output of the generator. When the current consumption is high or the battery is discharged the system is able to increase the idle speed.
To minimize the engine drag when starting the engine, the PCM controls the generator. The generator does not produce any output until the engine has started. The PCM then progressively increases the output of the generator.
The PCM controls the operation of the charging system warning indicator in the instrument cluster. The PCM is therefore responsible for turning the warning indicator off after the engine is started and illuminating it under fault conditions (when the generator is not generating the correct amount of current with the engine running). The warning indicator will also be illuminated by the PCM at key - on engine off and stall conditions.

Honda S2000 engine installed in kit car. How do I wire alternator

Unfortunately the Honda alternator is regulated by the ECU, which allows the ECU to intelligently reduce alternator engine loading to improve fuel consumption. The intelligent system uses an electrical load detector (ELD) located near the battery to control the alternator output voltage. A two wire alternator has an inbuilt regulator that will always generate the required charging voltage. When a battery is fully charged and the electrical loading is low there is no need for generating the charging voltage, in this situation the honda alternator will reduce the output voltage to reduce engine loading, hence improved fuel economy.
