Thanks for the help and information. Batteries were just used up. Yes I agree, not a big fan of the Champion gel batteries. Have a great holiday.
very common problem
measure the battery voltage with the truck powered up
then measure the voltage at the terminal board left hand front
position 2 the white wire
maximum allowable difference is 0.5v
finding the voltage drop can be difficult but check keyswitch
we are fitting a lot of relays to overcome this fault
When the customer says ,"batteries die to fast", is it the gauge showing low or the truck moves slow? I have seem battery indicators go bad and show dead batteries when they are actually ok. Just a thought. I am not a fan of the Champion batteries, I have come across a bunch of bad batteries from them.
