hey. Everyone what's up I haven't been on in awhile. But anyways there is some kind of short in my electrical system at night my head lights dim and the gauges dim as well. my system is not huge or anything so anyone have. Any clue??

 

did you say they dim @ idle or when you letoff the throttle?

 

check the voltage off your alternator at idle, see what it says...give it cruising revs and see what it says(get a buddy lol)

 

I was testing it last night and it would go to 3-4 lines passed 14 volts right after every wot shift but while it was wide open it was 3 lines below 14 so I'm at a loss

 

12.8 to 14 is good....do you have corrosion on your battery terminals? Unhook them and clean em with water and baking soda.

 

You think it could be a short or a bad ground??

 

Actually, disregard my last comment..battery doesn't do anything when the truck is running...still a good idea to clean your terminals though.

Turn your system off and drive around..see if the problem is still there. I was getting dimming off of a 500 watts, on stock electrical.

 

Ok I will. I found some more stuff out when my ac. Is on and I roll both windows the ac shuts off untill I let off of the switch.

 

Power windows actually draw quite a bit on the system. Everything else works ok in the truck though? does the battery go dead after a few days?

 

i only have a JL 500.1 pushin my sub and it makes my **** dim.
