Re: RXV not working after Controller Upgrade
With key on is there pack voltage at the two small terminals on the solenoid?

Re: RXV not working after Controller Upgrade
I still say it is your solenoid.
IMHO It was probably 'on the verge' before you sent your controller to Bob. The pitted contacts in the solenoid now have had time to corrode and get even worse without any use over a week and a half during controller programming. Plus, the controller is asking for more thru the solenoid after the Bob touch. |

Re: RXV not working after Controller Upgrade
Voltage at the smaller terminal connected to red wire (key+ I think?), it stays ~48v, does not decrease like the large terminal to b+. I assumed the other terminal was ground. I’ll check that terminal in the AM. Ordered a solenoid today, they will allow me to return it if that is not the problem.

Re: RXV not working after Controller Upgrade
Pack Voltage at both small terminals on the solenoid. The terminal going to B+ controller is the only one that's draining. It resets when the key goes off and then back on, but drains again quickly.

Re: RXV not working after Controller Upgrade
Okay just to validate, put one lead on a small terminal and put your other lead on the other one. Does that give you pack voltage when the pedal is pushed? If so I am going with a bad solenoid as well.

Re: RXV not working after Controller Upgrade
Once it is confirmed that the solenoid has energized, there should be pack voltage on the controller side of the solenoid. Any voltages lower than pack voltage, replace it. It can only be voltage dropping across the contacts of the solenoid.

Re: RXV not working after Controller Upgrade
I’ve been using pack - as my ground on these tests. I will check putting leads on the smaller terminals to see voltage, but using battery ground 3 of the 4 read pack voltage.
Replaced the solenoid today, same symptoms. The solenoid terminal headed to b+ controller is draining from 48+ to zero every time the key cycles back on. |

I had a similar issue with cart not moving. Replaced solenoid and it is working

Re: RXV not working after Controller Upgrade
Unfortunately the new Solenoid did not do it for me.

Re: RXV not working after Controller Upgrade
I put your controller on the bench.
List of old errors that I had cleared before I reprogrammed it. Error Recorded -------------------------------- Throttle Wiper EM Brake Failed to Set Stall Detected Buzzer Driver Off EM Brake Coil Missing Main Coil Missing Throttle Zero Check Supervisor Watchdog -------------------------------- These errors did not re-occur. New errors that were recorded after I mailed the controller back. Error Recorded ----------------------------------------------------------------------------------- Main Contactor Welded - It really has/had a bad solenoid! HPD/Sequencing Fault--- Turning key on with a pedal not fully up Controller Overcurrent---- Reads too much current draw, even when there is none. Supervisor Comms-------- An error indicator ----------------------------------------------------------------------------------- Controller Overcurrent is a persistent fault, and it re-occurs each time the controller is powered on. This would be considered a fatal error. FSIP could likely repair it, but you might spend more by having it repaired vs just buying a controller from them on eBay. https://www.ebay.com/itm/152355026624 Bob |
