OK, who here can claim to be the master of electronics when it comes to the wiring, etc of our cars?

Everytime I put in the rear defog, my battery guage drops into the orange. If I give it gas it goes back up. I've replace the battery and had the alternator tested. So those two aren't the issues. The belt is tight so I know the alternator is charging the battery properly.

Oh yeah, and my rear tailights are acting wierd. When I put the signals on, instead of all the bulbs flashing on and off together, they alternate, kind of like a cop cars does when he has his lights flashing.

My Cruise control is no longer working either so maybe it's all linked?
Any ideas?

 

Sounds like you have a power to ground fault in your defoger. When you turn on the fogger, the power and ground wires could be crossed somewhere causing a fault. It would prolly be hard to find.

 

Beast96Z.........my thoughts exactly....He must be the electronics master!!!

Good Luck!

 

It is what I do everyday.

 

The defog does pull quite a bit of juice and our alts are not known for putting out a lot of electrical power at low rpms. You could always remove the breaker and put an ammeter across the terminals in the fuse panel and see how many amps are being pulled with the defog on.

You could also have a bad ground or socket in the rear lights. The cruise will act up just like the ABS will, if the correct resistance in the tail lamp harness is not there.
