Does anyone know what gauge wire is supposed to run from the ignition switch to the solenoid on a 6 volt system? 54 Bel Air, original six banger Ron Francis wiring harness, new starter and solenoid, 02 battery cables, 6 volt alternator. My problem is the solenoid clicks more times than it engages. Doesn't matter if it's hot or cold. Starts immediately and every time jumping between posts with a screwdriver. I don't know what gauge the wire is that was supplied with the RF kit, but it looks a little small. I think it should be an 8 gauge, not sure though. Thanks for any help.

The shop manual diagram shows the switch to solenoid wire as 10 ga. However, If you can find 8 ga wire lugs that will fit the switch and solenoid terminals, I can't see any harm in using 8 ga wire.

I think you need a new solenoid. The large contacts inside the solenoid are either dirty or burnt. When you hear that "click"- it means that the plunger is working but not making contact to spin the starter. bobt

It's a new solenoid that works perfect when I jump between the posts with a screwdriver, and that's the reason I'm thinking the wire coming from the ignition to the solenoid may be too small. I tested it by connecting battery cables from the battery in the car to the starter before I installed the starter. When I mounted it to the engine all I got was click, click......... I'm game for anything so I'll take it apart and check it. Thanks for the suggestion.

Hi Pale warrior, I would go with what Ray said as the Ron Francis stuff is designed primarily for 12v which is what 95% plus of their market would be.
6V is very sensitive to wiring internal resistance and will go from go to no go real quick.
Also the whole point of a solenoid, which is just a relay, is that the big circuit is switched by the little one.
If you bridge the two big posts you are bypassing the solenoid. If you bridge the big post to the solenoid, which you shouldn't really do, its going to go real well as you just over supplied it buy a factor of about ten and it probably does have issues now if it didn't before.
That's the human equivalent of waking up your grandmother with a cattle prod.

Thanks Kiwi, I have double grounds mounted, and the battery cables go directly to the starter. I did connect the big post to the little post, but wasn't aware it could damage the solenoid, used to do that to cars when I was a teen and couldn't afford to buy parts most of the time. Thanks for the help.

My 54 powerglide has 8 gauge wire in the starting circuit. It has the neutral safety switch wired in 8 gauge.

Thanks Rustchip, I've been plagued with this problem for quite a while. Hopefully the larger wire will cure it.

Like bobt said, I'll be surprised if it's not your solenoid shorted out..

I still say it's the solenoid. Maybe you replaced it with a defective one(?) bobt

Pale warrior, Big post to big post doesn't do it, its the big post direct to the little solenoid that's nasty, either way is not good practice but lots of folk do it.

Have you solved the problem or do you want me to go further?

Hey Kiwi, I haven't worked on it yet, it's 10 degrees outside and my shop doesn't have a heater, so I'll wait 'till it warms up a little. I've ordered a new solenoid that's supposed to arrive Monday. I'll holler back with the results. I intend to change the wire from the ignition to the solenoid first, just to eliminate that possibility. If that doesn't work, then I'll change the solenoid. Hopefully I'll find the cause. I've been having this problem for about a year now. I change solenoids, works fine for a month or so, then starts acting stupid.

HI Pale Warrior, If you want to work out if it is a problem before the solenoid then what you do is take a light gauge wire about the same size as the one coming from inside but put a terminal on it and put it on the key side of the solenoid.
Run the other end back to battery power and flash it to see if the solenoid works as it should.
If it does then the problem is in the pre solenoid wiring or switch and starter button. So keep tracking back till you find the issue.
