Which coil do i use

[ytt105]

Continuing saga of stranded RR. I'm about to replace the electronic dissy from my 86 RR V8 EFI with one which has points. Hopefully I can than drive it home and wait for delivery of the Ignitor II points replacement kit I will order from the states.

My question is, I know I will need a Bosch electronic coil for use with the Ignitor II kit, but will this be OK for use with the points dissy or will it blow up the points.

If I need a new, points type coil, which do I get? With resistor or without. I have an external resistor I can use if that helps.

And yes I do need to replace all this stuff, its too far to go down the coast to collect the car and then find it won't go for the sake of a new coil.

should be able to use a standard bosch coil ($30 form supercheap) and most will say "use with resistor". Your external ballast resistor should be fine, run lead the normally goes to the + side of the coil to the resistor instead and then from the other end of the resistor to the + side of the coil.

One thing is see how many lines there are on the + side of the coil as one of them may be a +12V line from the starter to make sure there is enough volts for a dead cold (frozone winter morning) start. At this point in time that would not be your biggest problem but something to remeber for down the track

So an electronic ignition coil is too powerful for a points system?

An electronic ignition coil draws to much current for points, it will fry them in a very short time, the coil you need is a Bosch SU12R
