hey everyone I just fitted the lobe sensing pertronix kit to my old girl . now its all fitted up, it takes quite a bit to start. turns over for 4-5 seconds( before it took 1 second or less) then fires. also the tacho is all eratic while its idling to about 2000rpm then it comes good. any ideas?? im stumped. cheers

Hi Guys, Have a problem with my Dizzy, Installed a new Dizzy with a Petronix attached and bought a new Bosch GT40R Coil, I had a mate install the new dizzy however the issue I have is the resistor, I can't remember how the original wires where attached between the resistor and Coil and my Mechanic mate didn't take any pics before he installed the wiring, Ive seen the pics but doesn't help with my needs, any help be great…

Do you need a resistor with that coil?

[braz]

Apparently it says I do mate, i was told the neg goes to the neg side of the coil and the pos goes to the resistor, I just don't know what goes where after that...

[taslucas]

Hmmm, sorry I can't help with that. I fitted a pertronix flamethrower 2 coil and the resistor is not used.
I'm not sure but maybe the manual (downloadable from this site) may have a wiring diagram.
Or hopefully someone else will be along soon

Thanks Mate, Im gonna order a Flamethrower 2 of ebay, seems the easiest method to get the old girl going

Bosch GT40R Coil = need ballast resister, Bosch GT40 Coil + no ballast resistor

on crak there should be 12 volts going to the coil, while running around 9 volt using a ballast. But I would upgrade to a gt40 or a flame thower (im running a 1) as the pertonixs work better with 12 volts

Can anyone help with these wire, as to were they go when you get rid of the ballast resistor.
Cheers Russell

Check this diagram mate. Its from GQ Patrol Service Manual.

hey tusman, no there was no mention of changing anything on the car, the reason for this was that if somehing were to go wrong with the unit, i would be able to just re attach the old "point system" as a backup. what kit did you get? mine was the Pertronix Ignitor 1762LS(lobe sensing). cheers, nic

Is there a vendor on the forum that sells these?
