Idle Solenoid Non Stop Clicking (1 Viewer)

[Judger]

Good evening.

Trying to get the last few (apparent) quirks. I bought a carb from Trollhole a couple years back, and then took the whole cruiser apart...its together again. The weird thing that's popped up is the idle solenoid is not clicking non stop as soon as I turn the key to the ACC. The connection has good voltage, and is keyed on only.

Thoughts before I try a new part?

Thanks!

Do you mean the solenoid is staying on even when on accessory?

 

[John McVicker]

They often need a ground wire attached.

Sorry for the incomplete description. The solenoid, when I turn the key to acc repeatedly clicks, on, off, on ,off, on, off. It continues this when the motor is running and only stops when intake the power away from it. I have not bench tested it yet.

If it bench tests ok, then it's looking like a wiring/earth problem. I've never heard of these solenoids clicking on/off by themselves.
As john mcv says, the carb might be insulated too well from earth and getting a sporadic connection. Hence the need for a earth wire.

 

[John McVicker]

Yep, maybe run a separate ground wire. Or an earth wire.

Well, let us think about this. Solenoid gets 12 volts with ignition switch. What if the ignition switch is intermittent on the contacts ? The item to see this is oscilloscope. A meter may not respond that fast. My opinion is the ignition switch.

I’m with 1969fj on focusing on power. Disconnect the power lead from the wiring harness and run a jump wire from the + side of the coil to the solenoid instead and see what happens.

Okay, I'll give that a go. I don't have a coil, it came with an HEI, should I just run a jumper off of that lead?

is this a F1.5 Carb trolehole ?

or a Modified 2F later Trolehole with this style Fuel Cut Solenoid on it ?

if you have the Later below , i have your needed parts solution , and a pile of addional info we can discuss via a PM

let me know how and if i can help in any way ,

thanks matt

The in-dash ignition switch would be my next focus point as well , after a SOLID and tripple verified bench test of it .........

So...it appeared as though someone plugged the water temp wire to the idle solenoid. All good now. Thanks for the help everyone.
