+1 coil. Had one not totally fail but go weak enough to suddenly not fire the engine one day (but tested ok when cranked). Threw another one I had lying around from an EA 6-cyl and the thing kicked to life instantly. I did test the second one before starting and the difference in quality of spark was obvious. Had another one on my Corty just instantly fail while driving along one night to a girlfriend's house. No warning, no signs of failure, just one minute hooning along and the next, parked in a suburb far away with no life. Came back next day, new coil in, off she went. Coils are bitches of things and will fail at the worst of times. I prefer oil-filled over the solid core ones, as they seem to give a bit of warning before giving up the ghost.

Coils have thousands of windings inside that are separated by a very thin insulation that can break down both over time and many heat cycles. All it may take is a slight movement internally due to expansion from heat and the windings short out on each other, reducing output voltage or completely dying. Also there can be a break in said windings that might touch when cold but again when the whole thing is hot, open up and create an open circuit. Sent from my CPH1607 using Tapatalk

Yep, this.....^ ^ ^ ^ Don't forget to use the lube on the washers/nuts/under the bolt heads.

this issue is what i've had with coils.... got a spare to try?

I've had a hall pick up fail . 304holdens have dramas with them too . Something to think about . When it won't start can you do the 'msd check' and makes a spark ? I think you ground the white? mag pick up Wire

I used moly on the threads and heads when i torqued mine down... Smooth as butter right up to the "click" with no grindy noises or chatter Sent from my CPH1607 using Tapatalk

Sorry mate, was just checkin you hadnt plugged into the module and was overheating. Deans onto it. Standard coil should be fine, get ya out of trouble for now. Just if motor revs high and hard..... save for a nice coil. Jack. Sent from my GT-S7583T using Tapatalk

Thanks for reply jack, I don't run a module on the dizzy, I eliminated it and made spade terminals straight onto dizzy. Msd module I'll have to take a look then I guess cheers Msd digital 7 has pretty much all the features EDIT: while I'm here I should confirm that the MsD still has the red led flashing even when the motor won't fire. The tach also reads cranking rpm when not firing either; since this is picked up from the box, the box should be recognizing the fact that the motor is turning Sent from my iPhone using Tapatalk

Module on side of dizzy, take it off put new heatsink paste on it... sounds like overheating module.... If not recheck msd module. Does the msd7 take a curve tune or just for basic spark? Sent from my GT-S7583T using Tapatalk

Hi there,is the diagram still avaliable?I can't seem to see any photos.i'm about to put in my dash but have no idea where these hoses re attach to.

PLR do ok work and so does Jack Brothers, actually I'm yet to find someone better than Jack Brothers in Brisbane, maybe mendham engineering but they are expensive. If you need to send parts half way across the country to get it machined properly do it! machining is 90% of reliability

TRW. Silverline balljoints are long gone, unless a few stores have old stock laying around. I personally prefer to offer WASP suspension parts to my customers if they can wait for it to be ordered in. Unlike TRW, WASP parts are greasable, and normally around half the price.

They do awesome work at a fair price. I sent another customer engine down to them last week. It got there Monday and they are onto it.
