OK I eventually hooked the Back up alarm directly to the battery to test. I also hooked my meter to it as well So the back up alarm worked constantly until I either accelerated or used the hydraulics. I believe there is some kind of interference in this system. While hooked up this way I drove until 1A kicked in then it started working until I let it go back into scr range. So it only acts up when using the SCR Or transistor(not sure which one this is. I have tried putting a diode in the positive wire. I was going to try a different manufacturer for the Back up alarm. This Back up alarm SHOULD work. It should work from 24-48vdc
