1994 villager 4 seater 36v speed

Sleeperstang

Hey guys, first post here with my first cart. It seems like there is a speed issue with my cart... I can only reach 8mph on a slight downgrade at best. The specs seem to say 12-14mph is what i should be doing? It is mostly stock except for an led light bar that I added. Batteries are solid at 6.3v a peice and seem to last without dropping much. I verified the v-glide is contacting the last pole on the slide and cables are in decent shape... Resistors are in one peice, and the cables are all fine except being to small a guage in my opinion, but that's how it came factory ? any thoughts?

You didn't say how old the batteries are. Did you connect your DVM to each battery one at a time while driving (especially uphill) and watch for voltage drop? Even though they might read OK just sitting with no load - older batteries might fail badly under load and cause this type of problem.

Before testing anything else on a cart thats running - it is really important to thoroughly test every battery first - to eliminate them as the potential cause. Even if they are not the cause, you'll be sure of that and can move forward with your troubleshooting.

Sounds like a plan, any idea as to a what a low running voltage would be? And what a good limit would be? I'll check her for date codes and make a pass with a meter on it! Thanks

just did a test, fully charged the batteries were at around 37v and change, and when i was going uphil full throttle for a split second it would drop to 32v as i nailed the throttle, but recover as it went up the hill at 35.5v ... when it comes to a rest it would go back to 37v....it would seem to me that its all in check? i check the date codes on the batteries and all 6 weren't punched out for date as they should have been....

Sure sounds like they're OK based on what you've measured. Punched out? Trojans are typically date stamped on the post/land/lead area - what make are your batts (not that it really matters)?

So - 36v and its a Series Motor/Resistor Cart (which I'm personally not familiar with). Those are supposed to be easy to diagnose, though.

As a flat (uninformed) guess I would suggest you may not be hearing 5 distinct "clicks" when you depress the accelerator from slow up to top speed...maybe hearing only 3 or 4 clicks?

Lots of smart people on this site who know those resistor carts inside out. With any luck - they'll jump in here so I don't look too dumb with just guesses.

Sleeperstang

Yeah, I hear ya... I opened the v-glide assembly to make sure that it was fully sweeping the contacts, and it was... aside from voltage drop at the motor from the cables and terminals I can't think of much else it could be... as far as the batteries go they are 2200 series interstate deep cycle batteries... when sold they usually punch out the date of sale on them for warranty purposes... Mine weren't punched out by anyone...

OK - nobody jumped in yet - so read THIS THREAD (last entry). Its your next troubleshooting step.

My car is not a solenoid style cart, I believe the earlier generation used 5 solenoids to control speed, mine uses a v-glide sliding contact style controller ...

Here's a maybe. Can you push the cart by hand on flat paved land?(brakes dragging) My Interstates didn't have the date punched out either. They just wrote it on the battery in grease pencil. You can check and see if you see any remains.

Another thing tire inflation. Make sure it's correct.

And check the micro switches on the FNR sw. The reverse sw might be keeping you in the 1/2 speed reverse position. Make sure they are making and breaking correctly.

joesam

OK. You wrote resistors are in one piece which (I thought) meant you had resistors & solenoids. So you have a controller?
