No output voltage - Tripp Lite Lite Internet Office 280 UPS System

Check for voltage at the headlight connectors with the light switch turned on. If there is voltage but your lights do not illuminate, your bulbs are burned out. If there is no voltage, verify that there is supply voltage at the output of the light switch when lights are turned on. No output voltage, first check continuity between the switch and the lights, then check for voltage at the switch input. If there is input voltage but no output voltage, replace the switch. If there is no input voltage, check the wiring between the fuse panel and the switch.

Output voltage is based on 3600 rpm @ 60Hz. Sounds like your generator is over speeding slightly. Put a Frequency meter on the output of the generator and tune it to 61.5 Hz, that will get your generator in the 3600 RPM range.

a transistor has 3 leads,[emitter current, collector current, base current, i am going to give you list of options that the transistors can be used for and it depends on the configuration of the circuits.
input resistance, current gain, voltage gain, output resistance, power gain, voltage gain, (input and output power) + [input and output voltage] and {input and output resistance} + input and output power gain.

There should be a small white ceramic block on the firewall - this component cuts the battery voltage from 12 to 9 volts for the coil and ignition system. It has 4 wires and is called a ballast resistor.
You may need a book with the wiring diagram to be able to test it. You should have battery voltage going in and something like 9 volts coming out.
You can also run a wire with a fuse from the battery to the positive side of the coil to check the system. Disconnect the factory wire from the coil first.

Try to download the service manual to sony ICF 212, from internet. It will have all the details.

If you have a digital tester or analog try to check the voltage reading from the power supply if high or low or no supply.Check first following voltage location and section. * Check the AC voltage from ac cord to fuse and before the bridge type diode. * Check the DC voltage after the bridge type diode.if normal voltage. * Then check the voltage into the filter capacitor to regulator ic.the power ic.If theres a input voltage in the power ic,check the output voltage going to harizontal output.If no output the problem is you power output.You need to replace it.

you need to check first the power supply board whether the output supply 12-24vdc for the inverter board is stable and not flactuating..you can measure the output voltage with a multitester..you get a voltage output of 12-24 with the inverter board is connected or loaded to the system.be carefull of the high voltage at the inverter board..once the output is stable replace the inverter board or you can measure the output of the inverter be very carefull..the output range upto 500vac.be carefull..if the high voltage is stable replace the lamps...tnx and good luck..

Check voltage output of the power supply.

1. If below the indicated voltage on the output terminals, replace the capacitors across the output terminals with the same specifications.
2. If there's no voltage output at all and the fuse is intact, replace the 8-pin power regulator IC with same specifications.. It is usually DH321 IC.

some info from the manual (636) fault code 15. hope it helps??

o Be sure the battery is fully charged.
o The inspection is the same as "Input Voltage Inspection"

• Turn the ignition switch OFF.
• Remove the ECU (see this chapter). Do not disconnect
the ECU connectors.
• Connect a digital voltmeter [A] to the connector (8), with
the needle adapter set.

Standard: 4.75 - 5.25 V DC
*If the reading of input voltage is less than the standard
range, check the ECU for its ground, and power supply
(see this chapter). If the ground and power supply are
good, replace the ECU.
*If the reading is within the standard range, remove the
seat cover, and check the input voltage again at the sensor
connector. *Remove the air cleaner housing (see Air Cleaner Housing
Removal).
• Disconnect the atmospheric pressure sensor connector
and connect the harness adapter [AJ between the main
harness connector and pressure sensor connector.
• Connect a digital meter to the harness adapter leads.

D The atmospheric sensor output voltage is based on
a nearly perfect vacuum in the smaJl chamber of the

*If the output voltage is within the usable range, check the
ECU for its ground, and power supply (see this chapter). If
the ground and power supply are good, replace the ECU.
*If the output voltage is far out of the usable range, remove
the fuel tank, and check the output voltage at the sensor
connector [A] (when the wiring is open, the output voltage
is about 1.8 V).
