Reply To: 6V-12V question relating to 1956 Javelin

Thanks crosbyman, I Had already used Seafoam “Deep Creep” on both mechanisms.
I think that may have helped getting the starboard choke operational.
Still no luck Port side.

As per Dave’s earlier suggestions,

1) I did use a skip lead on the dash switch, no different effect in performance.
2) I measured the voltage across the ballast resistor while depressing the dash switch,
and got 7.8V.
3) I also measured voltage to the power terminal at the rear of the solenoid while depressing the dash switch, and noted 3.5V ???

I repeated the measurements on the other (working) solenoid, and got exactly the same readings.The only difference being one choke works, the other doesn’t.
Confusing to me.

To my mind, 7.8V across the resistor should provide enough voltage to operate the solenoids well,
I do not understand the 3.5V at the solenoids though.

Both solenoids perform beautifully when 12V is momentarily supplied.

Thanks to all for comments and suggestions.

Bill.
