Hot ignition key

Recommended Posts

I started my Vitesse today after a 2 month rest I noticed after a 15 min run the ignition key was quite hot but the ignition switch was cool. The gearbox cover was off and I had the heater on as I’d just replaced the heater hoses and was testing for leaks.
The outside temp was around 23C, could I have an issue,?

I haven’t noticed a hot key in the past, the key I used was an original brass 1968 issue so very thin nowerdays as I always carry it (good luck charm along with my US dime (in god we trust) of same vintage also very thin these days)

Any thoughts is there an issue?

Not sure which bit of the switch you touched? But the key's inside and I guess nearer the contacts? 

I had a problem with my GT6 switch last year, turned out the ballast wire was not making very good contact, but before I found that I'd looked up the price of a new one, £12 from Rimmers. Unusually cheap for them! Just checked for a Vitesse and they want £66! But that's a complete unit, no mention of just the switch. Somebody, somewhere must have the Vitesse switch?

The switch body I touched was the key barrel and it was OK re temp.

My Vitesse is a 68 Mk2 and doesn’t have a ballast resistor all 12 volt.

I assume the internals of the ignition switch is a simple sprung sweep arm and fixed contacts. Heat could be generated if the arm and contact didn’t make positive contact.

I have a couple of old spare ignition switch’s could change it but would keep the original key and barrel.
