86 EZ GO problems
 

I've been having ignition problems with my 86 marathon with a 244 robin 2 cycle engine. So far I've replaced the coil and cdi box, to no avail. I'm thinking it's the pulser coil. Is there any way to test the coil so I know for sure? Any help would be appreciated.

Welcome to the forum , I used the search feature and found this :
The way I understand how this system works, is the pulsar coil triggers the ignitor, which in turn triggers the ignition coil. The pulsar coil should read 75 ohms between the red and blue wires. If not, replace pulsar coil. There is not a test in the manual for the ignitor. They say, try a known good one, and if it works, replace the bad ignitor. There are two tests for the ignition coil. You should have 2.88 to 4.32 ohms between the orange and green wires. (primary of the coil) You should have 9.36 to 14.04K ohms between the orange wire and the sparkplug wire. (secondary of the coil) There is a discussion in another thread about a modification using an automobile coil. Check with ScottyB he can probably tell you where to find it. Capt. Ed

Pretty sure i found the problem...the pulsar coil checked out at .14 ohms. Once I get a new pulsar coil and get her back together I'll let everyone know how it went.
