new to carts, got ez go question??

theclintonsx4

I just picked this up for my family today. Was told it's a 94 marathon 2 stroke?? I'm doing a bit of research and it appears he might be wrong. Any help would be greatly appreciated in identifying the year, model, engine, etc..... I was told the starter/generator was bad but the wiring looks to be a mess, but before I tear into it I'd like to find the proper diagrams and schematics for year, model, engine, etc. Thanks, I look forward to learning as much as possible from you guys as I build this cart.

BTW, it doesnt turn over, attempt to start or anything and was told it just "died" on his father while riding????

Welcome to the forum. Your cart looks like 1988 (with the rubber nose) and early 88 as it has the 2PG engine (1988 was the changeover year).
If you go here http://www.buggiesgonewild.com/ezgo-...iagram-id.html you will find a place to get a manual. Also if you scroll down you will see some sheets of the manual which you should print out and at post #5 your circuit diagram. The 2PG is a fine engine and in a good state of repair will knock the socks off the 4 stroke boys.
Good luck with it
Dave

Thanks for the knowledge. Its greatly appreciated. So its an 88 EZ GO with a 2pg engine. I was thinking it was 2pg by reading some descriptions but was unsure because I'm a newb! Any ideas on the cause of the no starting problem? Any thing I should be aware of with this particular year and engine?

Dave Box

There is nothing to be concerned about the 2PG is a great little trooper, it just needs the simplest of mainenance.

We should first check the compression to see what shape you are in but maybe you are not ready for that yet so tell me,

When you turn on the key and depress the throttle what happens

a) nothing at all
b) nothing but I do hear something clicking
c) the engine turns over but will not start.
d) something else

The switch connected to the pedal engages but nothing else happens. It sends 12 volts out of the switch to the coil. I just started diagnosis and am printing some schematics as I type. The solenoid doesnt appear to engage so I'm gonna try to figure out why. Any ideas? There are two small wires on the front of the solenoid and one is not connected.

Dave Box

So you picked option a) and the solution is very easy. Insure the cart and next month torch it. Oh no wait a minute that's what I did.

What you should do is get the wiring right. On one of the small terminals of the coil you will have a collection of black ground wires one from the big F-R switch, one to the regulator and one to the ignitor. The other small terminal has three colored wires. One from the microswitch on the accelerator, one to the ignitor and one to the coil. So with the key on and the throttle depressed you should see 12 volts on one side and that should fire the solenoid which cranks the engine. If you have wires missing then that needs to be resolved before we both get much older.
Here is a most useful tip. From the negative of your battery will be a cable that is bolted to the frame, from there is (or should be) a cable bolted to the engine. A very common source of problems is a bad ground so remove that bolt on the frame and clean the frame to bare metal. Clean the cable lugs and bolt it up again. Also if the strap to the engine is missing replace it. Without that strap the engine will try to ground through the choke cable and sometimes it will and sometimes it won't, either way you will eventually rip your genitals off in rage.

So check the circuit get those wires on and clean and let us know.

Welcome to BGW!
1st picture looks like you have a driver for your cart already!
Very clean cart and Dave will get ya going, I'm not up on two cycle electrical but will follow along to learn and for moral support!

I think she'll be a passenger, but my 11yr old thinks she's driving! So....I've messed around with it this evening and found a few things out

1) It runs! If I supply 12 volts to the solenoid manually from the key switch or battery she fires right up both forward and reverse.

2) The coil has 2 wires on the positive side, one to the microswitch and one yellow wire that goes kinda behind the polarity switch to what I guess is the ignitor???? It has one wire on the negative side which goes to one pole of the solenoid. The other pole of the solenoid had a dangling blue wire that was not connected to anything on it and thats the side that if 12 volts was applied manually the cart fires right up.

3) The only 12 volt switched source I could find was coming from the microswitch to the coil and if I tapped into that for the solenoid 12 volt supply nothing happened. No click, no turn over, no start, nothing.... but 12 volts registered on a volt meter tested at the solenoid????? I dont understand why that wouldnt start it?? Again 12 volts from battery or key switch starts it right up but 12 volts after the microswitch does nothing???? Is there another 12 volt switched source to receive 12 volts from? I thought it would have to come from the microswitch seeing as how the gas pedal is basically your on/off switch on the engine???


Any help is greatly appreciated. Thx

Dave Box

Well that's all jolly good news, at least the beast runs. I think that we only have to sort out your wiring and we are done.

The battery positive has a large cable to the solenoid. This point is also used as a junction box to feed 12 volts to the ignition switch. With the switch turned on 12 volts is fed to one side of a microswitch which is operated by the throttle pedal. This 12 volts now goes to one of the small terminals of the solenoid. This same terminal is again a junction to feed 12 volts to the ignitor and the coil but only when the throttle is open.
You say in 3) that the microswitch feeds the coil, this is not correct. The only place that microswitch feeds is the solenoid. This you should correct. With this rectifed the cart should start on the throttle.
It seems like you have a great handle on how this works so if you can trace out the wiring I think you will have it sorted.

If you need more assistance shout out

This should help you out a bit too ...
