HD5 Starting Issue

[Outhouse]

I recently purchased a slightly used HD5 and having an intermittent issue with the starter.  When trying to start, the starter engages then immediately disengages.  It acts like a failing bendix.  I replaced the starter with an aftermarket unit and still had the problem so I took it to my dealer and they replaced that starter with a factory unit.  I got it home and a couple of days later the same issue again.  I returned to the dealer and they replaced the starter yet again.  Unfortunately, still having the same issue and not keen on going back to the dealer.  Eventually I can get it started but not before major frustration sets in :(. Any input from others would be very much appreciated.

To me it sounds like an electrical problem. Like the power is intermittently cutting out. Possibly broken wire or maybe even key switch/ignition contact is bad.

I think that the starter requires either that (1) the transmission is in park OR (2) the brake is depressed. As a test of a failing <Park> signal, I would suggest that you always start it with brake depressed. If it still cuts out then at least you ruled out a signalling issue.

Thanks for the feedback.  To further clarify, it doesn't appear to be electrical since the starter continues to "spin" if you hold the key in the start position.  Its more like something you would find in a car starter with a bad Bendix.  It just doesn't stay engaged long enough to turn the crank.
