Hello all, I recently had to replace the pump/motor on my powermaster, (Thanks Hank Terry), it was leaking brake fluid and blew the 30 amp fuse. skeptical of what caused it I installed a new motor and ran the diagnostic tests from the tech section. Everything measures up fine on my motor run times and the unit does not self-cycle (no internal leakage) the new motor would run every time I applied the brakes, so I replaced the accumulator. now the motor runs every other time I hit the brakes, which still seems too much, I do not have easy access to another pressure switch or anyone else local that could check for me. Could someone with a good working unit tell me how many applies you can get before the motor has to recharge the accumulator and post what they find here or drop me an e-mail at rrobb10@comcast.net Thanks everyone.
