Par car goes in reverse not forward

[jterr]

Trying to help out a elderly couple with their parcar. They put new batteries in and it now only goes in reverse. It is a 48volt full electric , can't find a model . Has everything but kitchen sink though.
Put new key switch which I believe is only thing that makes it go forward or backwards.
Any suggestion what to check would be appreaciated.
Thanks

Note the little green lights aren't coming on but the backup warning is

had a couple of par cars really neat carts,, don,t remember key switch having anything to do with forward or reverse mine had a rocker switch on dash,, might look at that switch and see if possibly a wire came off for some reason you are getting current to it or cart wouldn,t move either direction,, there used to be a fellow that worked at par car think he was listed as tech on this site might ask him

Yea I asked a Tech some where but no response yet.. I think it is wiring as some readings where shouldn't be. I think there is what looks like a risistor?? on forward coil but not sure what it should read

Can mod move this to a Tech person please before I lose any more of my hair trying to figure this out--LOL Thanks

Can you put the VIN up here?

[jterr]

where do I find that

Here's a sheet showing where to look by model

I can't post pictures..
I found on steering wheel
-5EDZ-31392-E2
on frame
348-00 SHIFT 1
on motor
69200-89A AC1 4001
on the seat it says Elite
It has 8 6 v batteries. The F/R is in the key switch on dash and has 2 little green lights on each side of switch, which are turn signals...

5EDZ-31392-E2 is the VIN, it's a 2002. The rear fork tube was made on the 1st shift, 348th day. Seat was a custom Florida seat, their "Elite" branding.

Was actually made in September 2001, it's the standard P4 Eagle, 48 Volt XP version. You would use the 96-2000 manuals for parts and service.

Wiring is in the parts manual, page 7-2. XP Troubleshooting is in the service manual, page 8-32.

It will be a challenge, no doubt about it with those solenoids. Have seen the issue be the key switch, the diode and/or solenoid.

This is what I have done.
1-I reversed the 2 F/R Coils- nothing changed still went in reverse not forward
2-switched the S1 S2 wires on motor and it went forward
3- I checked the resistor on the main coil and got a .25 ..ohm reading so I think it is ok
You say could be the diode. Is there a way to check?

Has new key switch and new batteries . My friend said it was working ok before she replaced batteries
