ez go gas marthon clicking

[gcart715]

I recently got this ez go 2 stroke marathon from someone off craigslist, and I dont know too much about golf carts. It needed a battery and a pulley, so I hooked a battery up to see if it would turn over but, as soon as I turn the key all I hear i clicking. I still havent gotten the clutch pulley but would the pulley be the reason its clicking? any info is greatly appreciated thanks.

First off check all the grounds. Battery to frame-frame to engine sometimes a visual inspection is not enough.Remove them clean and sand all grounding points this is the very first step. Also be sure your battery has a full charge. By pulley do you mean the driven clutch the one on the rearend ? If so that would have no effect on the engine not turning over. The Drive clutch has to be in place as the starter/generator belt is attached to it and this is what turns the motor over. Please give us a year on the cart or some numbers off the tag mounted on the passenger side vertical panel and we can go from there. Welcome to BGW were all here to help.

thanks racin I appreciate the help, the golf cart is mising the pulley on the motor not on the axle. But the serial number is 760719113389

I would think it's an 89 is the muffler horizontal ? The starter/generator on top of the engine ? if so you can check to see if it's turning while depressing the pedal when you here the click. If so thats good news. Good used drive clutches are hard to find but you may luck out in the golf cart parts forum and post a WTB drive clutch.

I dont think the generator is on top and the guy i bought it from told me it was a 70s ill post a pic of the motor and tell me what you think.

gcart715 your right it appears to be a 79 vintage with a internal starter/generator and there has been many post about these as parts are almost impossible to find. Don't want to bust your bubble but you may want to wait until one of the other members jumps in that knows about theses. Wheres DAVE BOX when you need him. He's the man on here as are many others. There may be other options for you as a different engine but as for me I DON'T KNOW sorry hang in there

Hello gcart,

First off here is a little history of the early EZGO gas carts.

-In 1976 the so-called '2pg'--a 244cc, Fuji Heavy Industries/Robin Engine--with an internal starter generator (st/gen), became standard. Repair parts are still available except for the crankshaft assembly, the voltage regulator/starter relay and the internal st/gen stator & field.

-In 1980, an external, Hitachi brand starter generator was introduced and the engine was modified. The crank bearings, drive clutch, point set & condenser, voltage regulator and the engine frame all changed.

-1981 ushered in an electronic ignition system, which did away with the golf carts point set & condenser altogether, and the point activator lobe on the crankshaft soon went away too. Except for the addition of an oil injection system, this engine went virtually unchanged until 1989 when the 3pg golf cart engine replaced it. Although the two engines are similar, many parts are very different.

You will note above that many important parts for you cart are no longer available. I mention this only because I would not want you to spend a huge amount of money on say a new gas tank only to find that the starter was shot and cannot be replaced. In addition that is not a pulley that is missing it is the drive clutch, (it is possible that the original owner removed a valuable item, sold it separately and then sold the cart), a new clutch is going to be ~ $260.

I am sorry to be the bearer of this miserable news and I appreciate that this is not the greatest start to your week, however maybe we can salvage something here.

If you do get this running you might find a used clutch and you can get it mobile. The first step will be to ensure that all the grounds are secure. There should be a bolt on the chassis with three grounds, one to the battery, one to the direction switch and one to the engine. All of these must be clean and tight.

Next we need to see if the engine cranks. That clicking is (hopefully) the solenoid clicking. It is quite common for the solenoid to form some corrosion internally and fail to make the connection. I suggest that you locate the solenoid and place a direct short across the two large terminals. If the engine cranks we have diagnosed a solenoid issue. If it still does not crank then we may have a starter issue. At this stage you need to decide if you want to investigate the starter and see if it is as simple as the brushes being worn.

But first see what happens when you short the solenoid.
