    Run a ground wire from the batt negative to the breaker panel ground see if that helps.

    What are the voltages doing WHILE you are pushing the start button. My guess is that the 12V is probably going away when y0u load the circuit by pushing the start button. If so you need to start sampling the voltage along the pathway back toward the batteries until you find where the voltage doesn't drop off when you push start.

    if not you may have a bad relay contractor along the start pathway. The recycling symptom sounds like a supply side component(polarity diode) or connection though...

    Yikes your under truck Troll has a twin.... that really sucks.... hopefully though solving one gives you insight into solving the other..... two birds with one stone kinda thing. Best of luck.... am sure you will figure it out.

    with fresh batteries the batt voltage drops to 19-20 volts from 26. maybe starter is drawing too much or is jammed?

    Run the ground wire. Or the polarity box is bad.

    Thanks but run ground wire where? And what is the polarity box? Under the air /hyd pump? How to bypass it?
    What is notable is the voltage drop on batteries when starter is engaged. 26 volts to 19 volts indicates a huge current draw so how can there be a problem with polarity box, if it was bad there would be no draw? Plus starter cable goes right to 24 volt side of battery not through the pol box?

    Run a temporary ground wire from the negative on the batteries to the ground on the pdp. And you can run one right to the ground strap coming off the starter going to the frame rail.

    4 NEW interstate batteries 4 weeks ago. Now 2 completely dead and not chargeable, 1 VERY low capacity and 1 good. Never had any luck with interstate 6TL. So problem solved.

    I find if the interstates go dead they don’t come back. No one else around me carries the 6tls though.

    The 2 that were DEAD show 13 volts, charge at 5 to 8 amps and with a load instantly go to 0 volts. ??? 3rd one shows 13 volts, with load goes to 8 volts and heads for 0 in a couple seconds.
