I have worked on old cars since the 50's. So I am familiar with 6V solenoids and six volt systems. But this has got me stumped big time. I am running a six volt system on my speedster. I wanted a ignition switch to off and on. Everything is hooked up correctly? I had a electric guru come and look at everything I had done. Getting to the point, there is a button on the solenoid, if you push it, the motor turns over like it should, but if you turn the key to start it will turn over not as fast but the solenoid chatters like a low battery. New battery, replaced solenoids 4 times, good ground. What is going on? Thanks for any and all help. Remember the Vets. Sam
Check the voltage from the starter switch at the solenoid , you may have low voltage to the solenoid that will cause the chatting, good luck
Could be that the trigger wire should be grounded instead of hot, and it's now using the starter for a ground. Test for continuity between the trigger post and the post hooked to the starter. Hope this makes sense. George
Could you be using a positive ground solenoid in a negative ground system? If thats the case, you might try a push button like the V8s used, single wire grounded thru the case of the switch.
Use a stock starter button and use the solenoid for a paperweight
There are two basic types, continuous duty and instant duty. Continuous duty are used on RVs where they stay connected while you are driving, instant duty are used for starter circuits.
Dave may have a point and there are 2 types as he says but I'm not sure if that's your problem. Obviously replacing parts hasn't solved it so it's something that's still there. What exactly does this ignition switch power? You say it cranks normally with the switch off and the solenoid chatters with it on so there's something (drain/short?), going on. Is it a 3 wire or 4 wire solenoid? Absolutely sure about grounds? Not sure if that's critical as it operates with the ign switch off. It's a small coil that operates the solenoid. Doesn't take much power to operate it either. I'd start with a test lamp on the solenoid activation terminal. See if it's power that's jumping in and out causing the chatter. Get back to us. By the way, stupid question: ignition on. Is the timing correct? It's the solenoid chattering and not the engine misfiring.
