View Full Version : electrical problem?

05-09-2005, 06:15 AM

power cutting in and out. mainly at night when using headlights. lights go very dim. when i step on the clutch, power is temporarily restored. when i come to a red light and let my clutch out, my truck dies. my radio is choppy. i will occassionally hear clicking near my glove box. the seatbelt and emergency brake lights come on and off. wipers will go very slow.

at first we thought it was my altenator, but then my friend thought he had it narrowed down to my combination switch (controls my headlights, highbeams, wipers). he replaced the whole piece and it seemed fine at first, but problem still occurring.

sounds like a short.have fun following the harness.try disconnecting one item at a time and see if the problem goes away.may help in narrowing down the short.

i had this problem before, it was the power wire from the alternator, it was old and cracked. i replaced it then my alternator regulator went, now im always charging at 18 volts

mine did that when the alt packed it in.

I had the same problem in the months before the spudspudspudspudspud trip last year. It was really frustrating because everything would seem to work fine, and then the charging system would stop working and everything would die. The next day it would be fine etc. I replaced the alternator with a one from the wreckers ($50-$60 I think it was) and have had no problems since.

One other thing you may want to check first is where the ground cable bolts to the block. If this connection is loose the battery will not charge properly either.

Even if I don't have anything polite, intelligent, or even remotely on-topic to contribute, I try to post anyways.

[7]Take it to a Battery place and get them to do a load test on the battery to see if there is a short inside one of the cells , also they can put the same test on youe alt. This is usaly a free test... [cheers]

thanks so much everyone. well the past four days have been hell. we have searched high and low. tested every connection, replaced the combination switch, alternator and battery. and lo and behold, last night we saw a little iddy biddy ground wire not connected. the one from the engine to the body. so glad it was found, but man, what a lot of work and that's all it was.

again, appreciate all of your advice!![36][36]
