Hi I need more advise, I wired ignition switch direct to starter after I got all new battery cables and direct ground to starter, the old rig still turns over slow but was able to get started so am encouraged. wired up to original wiring and it is turning over too slow to start, replaced one primary wire no change. My old maintenance manual says starters for hydromatic is different than for stick so this may the real issue, any ideas? Starter and battery were bench tested strong. thanks in advance and God bless.
