Have been having some problems with splattering and missfiring lately - its probably related to current to the dizzy (as say sometimes it'd missfire with the wipers on - turn the wipers off and its running fine - the same with the lights). I'm having eternal difficuties keeping the belt on the bosch alternator tight enough, so now the battery is sitting on approx 12.3v and 12.5v when rinning. This is low offcourse but I know that the lucas dizzy would run on it quite comfortably - does the Pulsar dizzy require a higher current to run?

I am not sure if the electronic ignition needs more power but do you have an electric fuel pump? They can slow down when the voltage drops.

It will take a bit more A, as the coil is 1.5 ohm not 3.0.
Check you have 12V there at coil, perhaps the bottom fuseholder or it's connections is dirty. That's where the coil power actually comes from. And the wipers, stop lights, blinkers, fuel pump....

Yea I was thinking - should I just rewire the coil positive terminal to run from the starter solenoid's "on on ignition" terminal? And is the standard mini low gauge wire overall sufficient for the 1.5 coil?

No I would just leave as is but check all connections from ign switch to coil, clean ALL the connectors on the fuseholders and the fuse contacts too.
They are 35 years old- get 'em shiny, then spray with WD40...
Carefully check any non-originally crimped ones, they tend to flex & fail.

i had the same problem in my van it was just the fuse box was all cloged up, like the doc said should check that first

Don't blame the distributor, it will run on 6V. If your system voltage is so low that it's causing a misfire and the lights are dimmer than usual, then the problem is in your charging system. Cure the problem, not the symptom.

Yup, sounds like a 'hot joint'. The voltage is fine until a little too much current passes through, then the voltage drops accross the joint. The common supply point for both the ignition cct and the window wipers is the fuse holders. Could also check the cable connection on the solenoid (I think it's the brown one that supplies the car electrics).

All garage work involves equal measures of enthusiasm, ingenuity and a fair degree of irresponsibility.

There are two brown ones - thick for always on and thinner for on on ignition terminals. Dizzy is fed by the thinner one (coz it runs from the on upon ignition terminal) so are the wipers - might be indeed related - I'll clean it up.

Oh and the solenoid is a 1 year old Lucas unit.
