The car appears to start and run OK, except for a new problem invloving a failing Vacuum advance which sometimes causes the revs to drop and rise again (probably the IACV cutting it to try and idle it?). The plugs are BPR6E and the ends are quite carboned up. I think the cap and rotor are non genuine as well, but I'm not sure, but despite being quite new, the contacts on the rotor and cap are in quite apoor condition with some sort of grey deposit on the cap and the rotor is just wearing badly at the tip.
Anyway, the issue is the hot coil. It gets so hot after a few minutes that you can't put your hand on it. The previous one (intermotor) actually blew its top off and oil spilled onto the exhaust manifold.
It now has a Lucas DLB198 on it. I've tried to clean up the earth under the coil with a wire brush and cleaner.
From what I see in the workshop manual, the wiring is correct. I've fitted a replacement link lead from the distributor module. There is a blue and white wire which links to the one coil terminal which could be from the ignition system, looking at the workshop manual.
Using a multimeter I get 12v into the coil and 7 out of it. I guess the heat is product of the difference in voltage?
The system should be 12v shouldn't it? It has been suggested that I use a balast resistor in the system to drop the feed voltage? Is this correct? I'm just a bit confused.com
