Halogen headlight taillight/brake light turn signals odo/speedo and horn. Here are the problems… Above about 6000 RPM the ignition will intermittently cut out. It doesn’t do it all the time. The higher the RPM the more it tends to cut out. Reducing RPM brings the lights back to bright. Above about 6000 RPM the lights start to dim intermittently. The higher the RPM the dimmer they get to where the lights almost go out. The engine runs fine if the RPM is reduced. The tachometer records some very high RPMS when the system starts to act up. Max RPM recorded is 19999 which is totally unreasonable. I am looking for some assistance in troubleshooting my electrical system and how to isolate the problem(s).,Start by disconnecting the cables from the generator coils and start up your engine. Problem still there? Do this to find out if your problems stems from the power side or the ignition side. If bike now runs fine, I'd look at the voltage regulator. Have you checked that all your connectors are ok? A grounding problem with a somewhat loose connector would be vibration sensitive, hence the problems at higher rpm. Is your stator plate securely fastened? Is your engine grounded to chassis? There might be a loose fastening in one of you engine mounts. Reply With Quote,,,

Nissan maxima 1994 rough idle

Start with one bottle of yellow HEET dry gas to rule out moisture in fuel tank.
Check your battery age tag. Most battery can last up to 48 months.
An aged/old battery will cause sign problem to ECU.
Next item to check is idle air control motor.
Engine on and all electrical off
Next turn on ALL electrical items at the same time.
high beams,radio,A/C,fan at full blast
An IAC that can not raise the idle will cause the problem you are encountering.

Please start with HEET and rule out aged battery first.
IAC is expensive component to replace.

My 1995 Subaru Legacy (high miles, over 200,000) lurches forward and back when I try to accelerate from ~65 mph to a higher speed. This appears to coincide with going above 3,000 rpm. The tach also goes up...

You will need a computer to accurately read the signals you are getting from the sensors in the engine bay, but my guess is that the MAF sensor may be acting up.

Ducati ST4s 2002 electrical problem

Hey Uca... sounds like its new battery time..(or the electrical system is not charging enough to provide voltage to run anything but the engine -Is this right??) .. take the battery to a battery shop and have the CCA (Cold Cranking Amps) checked, this is the only way to tell if your battery is good...replace if necessary..add a little grease on the terminals to prevent corrosion.. If the battery CCA checks good, its time for some electrical system checks..You need a friend to help with this... Using a multimeter (set to DC volts).. crank the bike...put the + side(red) lead to the + side of the battery and the - lead(black) to the - side of the battery.. with the engine running.. it should show 13.2 min.+ volts at idle.. when you rev it over 3500 RPM, it should go to 13.8+ volts minimum.. if it doesn't go this high.. you have a charging problem., with it rev'd turn the lights on high and see how the voltage should get a little higher..maybe .2 volts... Check this and reply to me on here..

.......Thanks.. mark as helpful and follow me.. thanks!!

Temperature gauge goes in the red. i replaced thermostat. engine does not appear to be hot. could it be an electrical wire causing the gauge to go into the red.

You most likely have a blocked radiator based on the vehicle's age, which will not allow all the coolant in your cooling system to circulate enough to cool the engine. The fans that blow on the radiator won't help much when this happens and at a stop the motor will get hot and the gauge will go in the red because the vehicle really is getting too hot. Just because you don't see steam erupting from the engine compartment does not mean the vehicle is not overheating. It is not very likely electrical short or related issue would make the gauge read high.

Check engine light says on . code 1401,what does it mean?

P1401 - DM-TL air pump motor current draw is higher or lower than expected (normal = 17-36 mA).

This is an electrical issue with the pump, it's not related to a leak in the evaporative emission control system.
