I’ve been chasing dead battery’s for several weeks now. This evening i started some testing and need some help. 1988;JD 2555 diesel. Both battery’s have their ground straps removed. I put the multi meter between the negative post and the ground strap and get a 4 volt draw with all the alternator leads disconnected and the key off and removed. I removed all the starter leads and get the same 4 volt draw with everything off and disconnected. When I began replacing wires one at a time I did not see a change until the power (hot) lead was reconnected to the alternator and I began to see an amp draw jump to 10 amps that counted down to and stayed at 4 amps in the key off position. I have not looked any farther or pulled any fuses yet to see if I can cut off the 4 amp draw. I have not checked the leads on the ignition solenoid yet. Any idea what might be going on with this thing.
