i replaced all 6 batts. after 3 days and maybe 1 hour of use their shot, each will charge but have no specific gravity, also each fails a 6 volt load test, meter reads poor. checked and rechecked each and every connection! also replaced 6 brass accelerator contacts. checked wire diagram and the accelerator wires to speed coils were reversed, so i wired them according to wire diagram. any ideas what could cause this? would also like info about coils, which one goes 1st, 2nd, 3rd when looking at it from the rear left to right. thanks everyone!!
