| check all your grounds, a bad ground can "feed back" and cause all sorts of problems and conditions. Easy check, use a long piece of wire as a jumper and go from the neg. on the light in question to neg. on the battery, if light gets brighter you just bypassed the problem if not keep looking |

found out the problem....
the wire had a rot (rubbed off)1/4 of the way....
it was reading 1. something volts from the rotted part back....
yeah i just rerouted a new wire...

dim lights are caused by low voltage;
measure supply voltage on the live side... if it is less than battery voltage you have resistance in that circuit (apply battery voltage to verify)
measure voltage on the ground side... if any amount of voltage is found on ground side, you have resistance in that circuit (apply ground to verify)
this all changes if the vehicle lighting is controlled by a bcm (multiplexed electronics) |
