Need some help with troubleshooting!
I have tried pulling fuses and letting the truck sit for a day w/ the battery disconnected.. no dice. I get NO codes either!
For the battery light, looking at the t/s-ing tree on the ford cd, it points to the alt, the voltage regulator or wiring. So, that should one or the other...
the one that's making me mad is the abs/ brake light! Both lights work, its just that no matter what, the brake light comes on dimly if I unplug any abs/brake sensor/switch. The brake light was kinda coming on and off with the parking brake out, so I figured it was the switch?
The ABS light is a new problem too... very odd indeed! I noticed a connector unplugged in the pass side kick panel before I did my little lighting mod, I didn't have a CEL or anything, so I hooked it back up and no problem.
Aside from the RABS sensor, which I haven't had time to look for/locate.
Now, If I unplug the parking brake sensor or brake fluid switch...the brake light stays on dim... leading me to think it's a wiring issue of sorts? I'm thinking the diode in the system took a dump... But I swapped it with the other diode and same results!
Arrrgh!Here's the system... Any ideas/suggestions?
