Altrax SPM-500 - Pre-charge resistor error code

klanel · 04-30-2016, 04:20 PM

I am getting 1 green/6 red which supposedly indicates a pre-charge resistor failure. I measured a 2v voltage drop across the resistor but to make sure, I disconnected one side and ohmed it out to .475K so unless the tolerance is too far off of .470k that is not the issue.

Error light does not start blinking until I press the accelerator down about 1/4 of the way. Just the throttle switch closing alone does not cause it to error.

I'm wondering if the controller may have an issue but it will be next week before I can get in touch with Alltrax.

By the way, their software seems to be lacking or its the old computer (XP) I'm trying to run it on. V2.1.8
