Plan to move the ignition coil to the nearside wheel arch. Two things I'm not sure about. 1 Does the coil have to be vertical? 2 Can I safely extend the existing wiring without causing problems with the in built resistance for the ballast. Mines a MK 2 Mike.

2. Yes. As long as you use normal automotive electrical wire the resistance change is negligible.
1. Interesting. To all intents and purposes, the functioning won't be affected. Strictly speaking, the coil design likes to be vertical due to the internal arrangement of components. I could only imagine this having an effect (in theory) in some sort of extreme cross country racing vehicle with lots of vibration and no suspension. Can't think this would have any adverse effect on a Stag.

Hi Mike,
For what it's worth, I mounted mine on the bulkhead (beside the rubber drain flap), as there is a threaded captive nut goes in behind the chrome grill, and I used that to secure the mounting bracket.
Most people seem to agree that mounting it upright is best, and I put mine on the bulkhead to get a way from the heat, get easy access to the vee and the dizzy bolts, and do so without having to extend the wiring at all.
hope this helps,
Peter

Thank you for that. Had thought of putting it there but thought the wheel arch might be cooler. Also thought about removing the insulation from the bonnet. Are ther any issues in doing this? MikeComment

My coil was fitted on N/S wheel arch when I got the car. Seems to work fine and it makes working on carbs, distributor or anything around the 'Vee' so much easier.
Only problem I've had is that I bought a nice new set of leads but I've had to stick with the old one for the king lead
Cheers
Julian

Hi,
Whilst on coils,does anyone know if the coil relies on the mounting bracket for earthing?

I don't think so. When doing the timing mine is removed and all seems ok. MikeComment

I remember back in the 70sUnipart rana big advertising campaign based upon a whole series ofof questions and answers referring to BL cars.
One of them which actually ran for a while until someone pointed out the possible misinterpretation was: "Can you fit a coil to a Princess?" :shock:

The centre high tension contact is + and gets its earth via the spark plug, which is how the spark occurs.

The (-) goes to the distributor and then to earth.
Coil body does not form an earth.

Doh! You are right, of course! The wire I had in mind is if there is a suppression capacitor attached! Of course, the wire goes to the points as that is how the coil works, by a continuous interruption of the primary circuit by the opening of the points.
I'll get my hat!

An old timer Triumph "expert" told me this,just shows they dont always get it right.
Mind you he is in his 80s,so will let him off.
