Broke down
« on: April 15, 2018, 07:30:18 AM »
Got the shovel together and got a good day in NE Pa. for a test ride. Rode 20 miles and it sputtered and shut down. Tried several times to restart, would spin over but not fire. Had gas, called a fried w/ a trailer. While waiting for him, I tried restarting several times. One guy who stopped to help held one of the 4 ( dual plugged) spark wires in his hand while I cranked it, no spark. By the time my friend came, ( 1-1/2 hours from stopage) with the trailer, I tried starting it 1 last time and it fiered up and idled perfectly. He followed me home, and at 1/4 mile from my house it started acting up again. Pulled it into the garage and it was running on 1 cylinder. I'm thinking the Dyna DS6-2 module is going bad with heat. Any suggestions on troubleshooting this problem? Thanks, Frank

How old is the Dyna DS6-2 module. NE Pa this time of year is kinda cool. I would start with checking for loose grounds.

Agree all connections need to be looked at. I'd then try a ride with the points cover removed, to allow cooling.

Frank it sounds exactly what I went through with my '77. I went through two S&S Hi-4 units, and the last time it failed I swapped points back in. Has been running perfectly ever since.

Please don't replace the DS6-2 with another one.

FOr just a couple of bucks more you could have a real electronic ignition instead of a points replacement system that relies on that antique random advance system.

Add a VOES to that ignition kit and you have the best bang for the buck HD ignition. It's even programmable!

This is what a DS6-2 (correctly installed) can do to your pistons!

I had a similar issue. Not one cyl cutting out so not the same but the power wire off the battery broke at the connection. I could start it and it would idle but when the vibrations started at higher rpms it would bounce the wire off the crimped connector and cause a breakup.
It doesn't seem like yours - but one more thingy to check.
