12 months or so back I wired up oztruck507's ute, including an ignition system I'd never worked with before... points....
12 months on and its breaking down a little - seems to skip a beat every now and again, idle is a little rough as it occasionally coughs. It was noted that the coil was red hot and when old mate went to change the coil it was spinning in its case.
Turns out that a bosch GT40r coil means use a resistor, not it has a resistor built in! bugga. So Im assuming that it was getting too many volts and was starting to fry the coil.
So the coil has now been changed, new plugs and leads, same issue. Could it be points? something else in the dizzy? Any suggestions on what to look at next? The car is racing this weekend at Colo and I'd like it working properly before he heads out to defend his juniors title.

dizzy doenst have a condensor hanging off it - (assuming thats the little cylinder jobbie hanging on the side). where does the condensor plug into, and what is its purpose?

To simplify, a condensor is basically a shock absorber for the electric current that is blocked/released as points open/close. This stops spark jumping across point gap (arcing). It usually mounts on side or inside dizzy, with body going to ground and wire connected to neg side of coil wire or to points connection. It MUST have one to run, so there must be one somewhere, but if they are faulty they will cause all sorts of running problems. Dont bother looking for more faults until the points and condensor have been changed! Wish I was a builder....or something else!
Cheers Jones. Will try it. Must have a condensor inside I guess.
Not sure what engine the dizzy's out of, as its an 8 plug head, 4 of which have been blocked off and a 4 plug dizzy has been put in. Have to open it up and take the condensor in.
Thought you'd given up the spanners to become a part time farmer? You can have my job as a technerd if you want it, Im gonna go work for Azteck.

Just a shot but try a ballast resistor. It allows a full 12 volts for startup but drops to allow 9volts once running.
Common on cars including Gemini's, if you take the resistor off the car will start to run rough, then miss and eventually the points will weld themselves together.
ha wolf, if the engine is a nissan it's proberly one of them old pintara 2.0l , pa 20 i think they where called. they had a twin spark ignition system , with 2 plugs per cylinder, 8 post's on the cap and a double ended rotor button ( not the double ended thing you were hoping for last night ) PS ,piss the katering points system off ,

Hey Wolf, what are you going to work as with aztek? I've decided to get him to prep my buggy now, so I hope your qualified! Just got to wait for him to finish Slows buggy, should be done by april though...so then I can take mine up. There's a drought out here, so I am still on the spanners, just hate using them on the buggy! If I had given up the spanners, then what would I be doing when I'm not 'part time farming'?
Not sure what I'd do for azteck - receptionist at the print shop maybe? for 150k, company car and time off for preping the racecar... :)
hmmm.. what could you do other than farming or mechanic.... you could join kuster in becoming a mardi-gras float driver. not sure how much it pays though. :)
