Alltrax SR48300 Low voltage error in reverse

bbirling · 12-02-2019, 10:11 PM

Mid 80's marathon upgraded with Alltrax SR48300 controller. HD solenoid new cables. Works great in forward but reverse not so much. If I am on a slight incline it will send enough voltage to get going in reverse. Switched cables at F&R switch. same issue. I get a low voltage error code on the controller. Solenoid engages as it should. Batteries at full charge.

Thoughts would be appreciated.

Thanks

Have you hooked up a laptop to the controller and check/ adjust the reverse percentage setting?

bbirling · 12-03-2019, 09:40 AM

Yes, Set it to 100% same as forward. When it is put into reverse, it tries to go but just won't, that's when it errors out. If I start rolling it a bit it will eventually take off. The monitor download is a CSV file and have no way of converting it for upload.

Thanks

Swap the cables at 3 and 9 oclock on the F&R.
If the problem reverses direction replace the switch.

As I stated in my first post, I swapped those wires already. Forgot to specify 3 and 9 o'clock. No change when I did that.

Thanks

I guess I didn't read correctly. You swapped 3 and 9 oclock cables on the F&R and the problem remained with the reverse speed. Forward have not been effected.

That is correct.

The problem sounds like it is in the controller. If there is a wire connected to controller J1 blue?
If yes, remove it and test.

With J1 disconnected the solenoid does not engage. In Forward or reverse

J1 blue not red
