I've been running my accel coil in a horizontal position for several years with no problem. Mine just dies like flipping a switch. It will crank while coasting but not start. It has to come to a complete halt.
One other thing that may or may not be related. Several years ago I added a short ground wire at the starter relay to use in case my neutral safety switch NSS) got out of adjustment. The last time before I drove it, it wouldn't crank with the NSS connected so I figured it was going to need an adjustment. So I connected the cheater ground and it started and I drove it and started it a couple times with no problem. So when I was looking at it the other day it wouldn't crank with the cheater ground. So I connected the NSS and it cranked ??? goofy.
Now the ignition switch has been replaced since I've owned the car. And I had it out of the dash when I was rewiring, all seemed fine. So I'm still wondering about the starter relay and the orange box. I checked the ballast resistor and it didn't show any signs of excess heat, although these newer one are enclosed in back whereas the older ones were open. I did tighten up the connectors so as not to add additional resistance.
Waiting for warmer weather to go for another short ride. I've got a replacement ballast resistor so I'll probably change that first. After that one thing at a time.

I've developed a problem after rewiring my engine compartment. The engine will just shut off while driving. No sputtering or anything it just shuts off like someone threw a switch. It will not restart while in motion but as soon as I pull to a stop it will start right up. It happened at 5 mph, 35 mph, and 60 mph. It has happened after driving 2 blocks, 5 miles, and 10 miles. When rewiring I soldered every connection and I eliminated the ammeter. I had driven it several times for up to an hour and never had a problem. And now it has happened the last 3 times I drove it. The last time it happened after driving 10 miles, but then I drove it an additional 30 miles with no problem. I'm running an orange box and an Accel coil.
When eliminating the ammeter the 10 ga. red wire that ran to the ammeter was relocated to the starter relay. A second 10 ga. wire was run from the starter relay to the black 10 ga. wire under the dash that had run to the ammeter as it supplies power to the dash. Just wondering if I have too much power running to the starter relay. I'm still running a stock alternator.
Any ideas?
