Hello all.
So I have a 74 z1 with a simplified wiring harness, just the absolute basics, running a dyna S ignition. It had ran great for about 5 years, but over the past year I’ve had a gremlin in my charging system. At first the headlight started dimming in higher rpm range, but it still started and rode fine every time, so I chalked it up to a poor headlight ground and kept riding. Over the past year it has died on me a couple of times, i tried swapping the stator, regulator/rectifier, and battery independently in an attempt to solve the issue, I got the headlight to stop dimming under load, but it would still die on me after a few hundred miles. The battery would start at 12.6, drop to 11.8 with the key on, start fine, but the voltage wouldn’t go up at all at any rpm level. Same symptoms no matter which part was replaced. I’ve got a long ride coming up so I wanted to solve that once and for all, so last night I replaced the stator and regulator/rectifier with the z1 enterprise stator, regulator/rectifier combo (non lithium option) and I put a new battery in. Stator is putting out 60Vac, but still no voltage increase at any rpm range. I am pretty confident in my initial wiring job, as I had years without issue, and there are no issues with the wires that I can see, grounds LOOK good, but I’m assuming something must be grounding out somewhere to cause these issues. Can anyone point me in the right direction? Could the dyna ignition be the culprit? It starts first kick, doesn’t draw with the key off, doesn’t go above 11.something at any rpm range, and shits out after about 800-1000 miles or riding. Any input is appreciated, and sorry for the long post!
