i would get a wiring diagram and a dvom (digital volt ohm meter)
use the diagram to figure out what wires to test for. look for the ground wire. in ohm mode connect one lead to the ground and the other to the neg terminal on the bat. should read 0.0
now set it to vol= not vol~ find the positive wire and put a lead on that then leave the other on the neg term of the batt. press the button. you should see 12.6 volts
most likely you are looking for a bad ground or resistance in the wires or connections
