1995 Medalist questions

New to the site. Have sat here for hours and am very impressed. Awesome that pros will coach the novices. I see the consistent responders and am hoping to pick you guys brain a little.

1995 Medalist (not a DCS) I believe you guys refer to this as a "series" cart?

1) Is it possible to use three twelve volt deep cycle marine/rv batteries instead of the six six volt batteries. I expect that the operating time would be decreased but would it be a significant amount? 20% less, 50% less? I happen to have some new batteries I would like to use them if this is a viable option.

2) Two years ago this cart quit suddenly while driving across the yard. I put it in the garage and have not messed with it since. My sons are now old enough to participate and we have decided to dive on this thing and fix it up. I know I will be replacing batteries next week but I need to address the original problem as well. I have a little better than 36 total volts now and am hoping to make some basic diagnostic checks with these old batteries.

a) I do have a solenoid click each time the pedal is depressed. I only have a basic electrical knowledge but while checking I discovered that I have continuity through the big solenoid lugs all the time whether the pedal is depressed or not-key switch on or off. I do not understand that but am wondering if that even matters and if I am possibly reading through the resistor that is mounted between the big lugs? By the way, why is the resistor even there in the first place and can they be bad and offer no resistance threreby giving me full continuity between these lugs. Also, am curious about the diode between the small lugs. What is it's function? I am getting a little better than 36 volts on both sides of the solenoid. Here is the big problem- there is an approximately 6 inch wire on one of the big solenoid lugs that attaches to another lug on what I suppose is the control box. This wire has all of the insulation melted off. Also, a small portion of the control box cover is melted. The kicker is I can see a small part of the insides of the control box and eveything looks to be intact. I looked closely. Not sure if the box was hot or the aforementioned wire caused the cover to slightly melt. This is a nice seldom used cart and has had no modification or prior repairs. Just before it quit it had developed a condition that may be a piece to the puzzle. If you were driving the cart and stopped for a second and then tried to take off again sometimes it wouldn't go. We discovered that by depressing the pedal numerous times it would take off again. When it stopped the last time it was under power at the time.

Welcome to the forum...

1- You Can use three 12 volt deep cycle batteries but your run time will be about half of what you'll get with six 6 volt golf cart batteries. The overall life of the 12 volt batteries will be short also. You best bet is to bite the bullet and buy the 6 volt golf cart batteries.

2- It could be several things causing this. Start with checking all cable connections and make sure they're clean and tight. Also check the cable connections at the forward and reverse switch to make sure connections are tight. Look for signs of heat of the switch board.

3- If the controller cover is melted chances are good the controller is bad. Replace the melted cable first and see if anything changes as far as the cart running or not. The resistor is a pre-charge resistor for the controller. Normally the cart will run without it so I doubt thats your problem. The diode only allows current to flow in on direction and keeps the current from back feeding into the controller.

Thanks for the info!! I will get started. Any ideas on what appears to be an "on all the time" solenoid?
If controller needed, any thoughts on best place for replacement. Is there a cart boneyard? New or reman? Do you sell parts?

if your solenoid is on all the time just replace it......................................................

The resistor can cause the voltage to show on both sides of the solenoid. Remove the resistor then check to see if the solenoid is stuck. If the cnroller is bad it can also cause voltage on both sides of the solenoid all the time.
