Hey guys! Well, my 81? 88? EZ-GO XI875 medical cart is running! I charged the batteries individually with my car charger, replaced the cables that link the batteries together, and got everything running. I bought a 36 volt charger online and hooked it up for an hour. The thing runs awesome and is actually pretty quick.
Couple of questions though... the first is, what are all the solenoids for? I have three solenoids. I THINK two of them are hooked up, and the third one isn't. They are hooked up in sequence, but the "excitor" or whatever wire that is, I don't believe is actually hooked up. How would I know? Would the cart go faster if all three of them were hooked up as apposed to just two of them? What is the purpose of having multiple as apposed to just one?
Second question is... I have a set of lights on the front of my cart. There are a number of leads that were hap-hazardly hooked up to various batteries. When I hook up the negative wire, two batteries down (giving it 12 volts), they are very dim. When I hooked it up three down, giving it... OOOH... I just answered my question. That's actually the POSITIVE wire, and since I just happen to be hooking it up to the negative lead on the next battery, that's STILL technically the POSITIVE lead from the 2nd battery, so it's ACTUALLY getting 12 volts.
Damn...
Ok, I guess my main question is, if anyone would be so kind as to explain exactly what the purpose of the solenoids are, what kind of voltage the excitor wires are supposed to be getting, and what the purpose of having multiple ones as apposed to just one?
Here's a pic of the cart in case no one has seen it...
Thanks guys!!!
