Battery Voltage vs Fus Block Voltage
Happy Holidays everybody....
Ok heres the deal..
I measure the voltage at battery and it reads approx 14.00 volts
I measure the voltage at the positive voltage bar and it reads approx 14.00 volts
I measure the voltage at the fuse box terminal and it reads approx 13.00 volts.
bottom line is the voltage at the fuse box is approx 1v to .5 volts lower than the battery, so how do figure this one out?????
These voltage where measuered while the motor was running,
Thanks in Advance
Brad

I would say the resistence of the length of wire form the batt. to the fuses, is this 13v hurting anything...sounds acceptable to me

Update..
Actually its my chassis ground, if I read any voltage in the fuse block to any ground near fuse block the voltage reads about 1v lower. When I read voltage to motor ground, the voltage is the same.... I measure the motor to the chassis ground and it reads about 25 ohms, therefore I have a chassis ground issue, going to replac my ground wires and that should fix the problem!!! I am pretty sure its the crimped conntecotrs, because I used 8 gague wire for ground...
