Does this wiring look correct?

Scottn29

I have acouple pics of the wiring in my cart. Its not hooked up. I am gonna change to HEI and put a new coil on it, then I want to get it wired and try to start it. I will check the grounds and resand them down so they have a good connection.

In the service manual I downloaded, I do not see 2 wires going to the coil, like this one came already wired. There is also a spade on the ignitor that looks like it should have had a wire go somewhere, but no loose wire is to be found.

I also am not 100 percent sure which hole the throttle cable needs to run through. I only have a choke and a throttle cable that I can find in there. In the manual I see 3 of them. The guy I bought it from said the choke was never hooked up. So I really just need to figure out how to get the throttle cable hooked up.


So here are some pics of the bay and one of the ignitor.

Hello I think that I can help you here but I must confess that your cart has me very confused and I thought that I knew the PG series engine pretty well. Here are my concerns.

1. It looks like you have an internal starter and generator which dates it as pre 1980.
2. You clearly have an ignitor which dates the cart as post 1981
3. I see no provision for the oil injector in the carburetor elbow which again dates it as pre 1980.

Have you owned this long and have you ever seen it run because it almost looks like someone has dropped a 1PG engine into a 2PG cart and to be frank that dog won't bark.
In addition did you remove the fan cover? That cover needs to be there to direct air to the cylinder. You should not run the engine without the cover or you will run the risk of overheating the cylinder and head with all the misery that brings.

To connect up the throttle look at your third picture. In the center is the throttle cable, it is the one with the spring. The throttle butterfly is on the top of the carburetor and is designed to spring to its fully opened position. So gently close it until it is fully closed and you will see which hole it aligns with. Remove the cable end and make sure that you do not lose the spring. Now remove the nut and poke the cable through the hole and pin the nut back on. Thread the cable through the accelerator lever which should be held in the closed position, now place the spring on and the cable stop. You should now compress the spring so that it is about 3/4 of its uncompressed length and tighten the screw on the cable stop. Whilst looking at the carburetor gently depress the accelerator pedal and observe that the butterfly opens.
The choke cable loops behind the carburetor to the choke butterfly on the back side of the carburetor. I think that when you look you will see how it fits.
The reason that you have seen three cables is that there should also be a cable which connects to the driven clutch. This is the governor and as the cart gets faster it will close the throttle, this is one of reasons for that spring being there. Many guys (myself include) have removed that cable as being unnecessary so if it is missing it is of no real import.

With regard to the coil there should be two wires one to the ignitor and one to the 12 volt side of the solenoid. When you depress the accelerator you provide 12 volts to the solenoid and the starter turns as well as providing 12 volts to the ignitor. Now the 1PG engine had 3 wires as in addition it had a blocking relay so once again I am confused as to what exactly you have here.

Might I suggest that you pull the fan off (which is easier said than done) and see if you have a set of points in there or a pickup coil. If it is a 1PG you might also consider that parts are now almost impossible to source.

Thanks for the reply Dave

I have not seen this engine run, was told it ran, but ran badly and had a weak spark.

I did not remove the fan cover myself. I do have it though. He had it off and said he was checking the points.



I hope its not the case of it being a 1PG. The model number on the motor says EC25-ds, does that help identify what model it is as to 1p or 2P?

Here is the manual for the engine in this thread

http://www.buggiesgonewild.com/gas-e...ce-manual.html

Page 56 does show a blue and yellow to the positive side of the coil and a black to the negative.


I also see info about a pulsar coil and to test that with a Ohm reading. but what I read says to test the blue and the red wires. Out of the engine where the pulsar coil would be, is 3 wires coming out and they are greenish, yellow and red. I tested every combination of those for a ohm reading and came up with nothing.

Dave Box

He said he was checking the points? I really hate to be the bearer of bad news but if the engine has points then it should not have an ignitor (and as a slight aside the coil should be bolted to the firewall not the engine). This is not to say that you can't make it work but the HEI mod is not feasible for a points based system.

On the passenger side of the cart there should be a tag with the serial number and the manufacturers number which should reveal the year of the cart. On the engine there should be a tag with the engine number and the year of manufacture (although due to age and heat the tag does fade or peel off). If you can find that information it may provide more clues.

The serial number from the cart is 79E11 T7I550

Our posts crossed in the ether. If you go here
http://www.buggiesgonewild.com/ezgo-...iagram-id.html
and scroll half way down you will see a diagram of a 1977 engine and you will see two wires on one post (the extra one being the blocking relay).
If you scroll further down you will see the 1981 - 1989 style with one wire on each post.

Perhaps I should reiterate that I am not definite I just suspect that someone has put an older engine into a mid 80's cart. I could be wrong, it has been known.

From the info I was reading the engine model I have came on 80-88 models, and then they redid it for 89-94. Do you know anything about that?

And if you look at the post above where I linked to the manual for the EC25-DS, on page 56 you can see the wiring diagram for it.

I am really confused now :(

Is it not safe to assume I have the right manual?

Scottn29

According to this post

It is a 79 model and a 1p. Does that mean I wont be able to fix it?

Dave Box

Actually the 79 is a very early 2PG 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 virually unchanged until 1989 when the 3pg golf cart engine replaced it. Although the two engines are similar, many parts are very different.

So with the non availability of the crankshaft assembly, the voltage regulator/starter relay and the internal st/gen stator & field you might want to think about what you want to do, but certainly there is a possibility of getting her running again.
