been reading the archives for couple hrs but am still unsure of which pertonix i have in my 72 firebird, it was installed in 01 by prev owner , it has no numbers on it but has module and mag ring that goes thru wts. is this the orig ignitor or ignitor2.
it is hooked up with black wire to - side and red to + side along with black and yellow on + side. it only has 9.5v on + side when running so thats what im wondering if it should be hu with 12v, it runs OK. also using pertronix flamethrower coil to match.
is it worth while to change the wiring if it needs 12v like the ign2 does like i said it seems to run OK ,thks.
