rxv voltage problems. jumping from 49v to 8v and everywhere in between

[rabbitreborn]

If it's in the main harness it is not for a voltage converter. I don't have a Danher controlled cart on hand to check or I would try tracing it for you.

Ok, here is the Wiring Diagram and Danaher Pinout that covers to 2010 RXV. I hope this helps.

no there is a motor test im doing on the rxv that is checking for short circuits and over currents and it is checking the ohm resistance on it and the test is showing .4 and they said the readings should be 0.0 to .02 my question is this test is saying to replace the motor if the reading is above .2 but could a bad motor be causing they crazy volttage readings? i dont really want to order a new 1500 motor but i will if it is the problem. i just wouldnt think i would be gettting all these crazy readings if the motor was bad. thoughts

And the Accessory Harness diagram in case you need it.

Not while resting. The motor is not being used at that point. Does it pass the POST for the motor? There should have been safeguards put into place in code to prevent any sort of uncontrolled software loop upon detection of any failed device during a POST.

The controller itself could be the cause of the EMI, but I doubt the FCC would have passed emission limits high enough to cause electronic disruption for any digital device such as this. That could be detrimental to radio communications in the area. Of course, if it's an isolated incident from that particular controller...

i am not smart enough to understand 1/2 that. **** it im just ordering a controller and we will see what happens

Sorry, I tend to get too technical at times and forget that I'm not talking to engineers. The electrical noise does seem to be coming from the controller, so trying another controller sounds like a good idea. If it turns out not to be the controller, I'm sure you'll need a new Danaher controller on another cart in the near future. Just be wary of swapping out for repaired controllers, when you do that you never know the history of what you're getting. You may end up with controllers that are worst off in the components that were not replaced.

Those Danaher controllers can be a real pain. I'm going to have to get one that at least has functional communications so I can set up an interface and get real familiar with its innards so I can help people better when they have issues with them.

i have another rxv in the shop that is getting a new controller so when it comes in im going to throw it in this cart and if it works i will just order another one for it. it sounds like it is because i have ioslated other parts of the system and still have the problem, so it sure looks like it could be the controller. i will post what i find out. thanks alot for all the help.

Your problem is battery or battery connection..
voltage is fine at rest ... but fails under load.

check connections/terminals/wires.

I think this is gonna be an expensive battery problem.
