Coil Location?

[Rich in Vancouver]

Hey Guys,
My 1975FHC has it's ignition coil mounted at the right front of the engine bay in front of the strut tower. This results in the coil lead being over 3 feet long. Is this correct? If not, where should the coil be mounted. I have wasted hours looking at engine bay pics and it seems that most of the photographers manage to avoid taking pics of their coil.

Thanks,
Rich

I did see lots of pics of nice Sprint conversions-Mmmmm!

Hi Rich,

My '76 FHC has the coil mounted on the right hand bulkhead(firewall)there are 2 studs sticking out that it's attatched to,quite low down.
All the best

Mine is close up to the dizzy on the stut turret tucked in above the pressure valve - but of course it's a UK car with RHD. Makes sense to minimise the HT lead length if you can.

AFAIK, the early cars (2.0) had the coil on the bulkhead and the later ones (like my '81) had it on the inner wing between the tower and bulkhead, resulting in a very long king lead to the dizzy. Rimmers catalogue indicates the change at VIN 200001 (41cm vs 71cm lead. No doubt somebody will know the factory/date when the cahnge happened, but as a '75 I would think that somebody has changes yours, particularly if the lead is around 3' (92cm) long.

Thanks chaps!
After seeing the Colonel's post I did a hunt and found the coil studs on the bulkhead where he indicated. The coil is back in it's proper location now, and I was able to remove about 15' of excess wiring and shorten the coil lead by over 2 feet. This has to be a good thing as the HT lead was routed along the cooling hose and I thought I could hear some sparking from it.
I can see why the previous owner moved the coil as it is very tight down there. He seems to have been one to take the easy way out and his lack of motivation has been causing me a few challenges.[:(]

Cheers,
Rich

Update: Took the car out for a run and it is running much better. The hesitation and rough running that it was experiencing are gone.
It's nice to get good results from a small job like that.
Oh yeah...Here's Dirty Dick's tech tip of the week: I had to shorten my new HT lead and had a terrible time getting the boot to slide on the wire. Oil, hot water and my old favorite, spit wouldn't shift it, but I did find what worked.....ahem*..."personal lubricant". Slippery stuff that![:D]

Hi Rich,
Glad you found what you were after and all sorted.
Go careful with that "personal lubricant" & wash yer hands after!!![:D][:D][:D][:p]

Rather than rob your stash of "personal lubricant" try Black Magic rubber restorer. It's a clear silicone, very slippery and is absorbed into the rubber. Probably not a good idea to use it for the "other". [:D]

"Black Magic eh.....I'm not commenting on that product!
Fortunately the task at hand only required a wee drop of the other!

The reason the coil was moved from the bulkhead to the inner flitch was because of fire risk. The original location was close to the petrol pump and petrol leaks had the possibility of spraying onto the coil, sparking and then fire.

I found this out in May 1985 after my own car had flames coming from the engine bay. And yes, it did survive and is the same car I have now. The only repairs required were some new petrol pipes. Amazing really.

My coil is now (unsurprisingly) sited on the inner flitch.

Good point John. I previously switched to an electric pump near the tank and have considered relocating the filter from it's current location near the coil. I had better get busy![:0]

BTW: Love the Bullet video. Thanks for your hard work!
