acuspark electronic ignition kit problems

[zhcj]

can anyone shed any light on this problem please

i have a 65 vit 6 possitive earth i have had 2 failed electronic ignition kits now from acuspark perhaps i have been unlucky they seem to last for around 700 miles or about 8 months then just break down with no spark to fire the engine. both have had the same fault

ive checked all i can think of on the car the voltage regulator is new and is putting out 13.5 volts at 2000 revs which i assume is fine. the coil is the correct one and was replaced when the first unit broke down just as a precaution.

ive used the supplied heat sink paste and its correctly wired up.

can anyone offer any advise in fairness to acuspark they replaced the first one free of charge ive yet to contact them re this second one failing. i may just have to buy another.

the car isn't used that much its lives outside under a carport and cover but its driven once a week at least even in the winter months  could it be that with an electronic module?

or could it be the car is + earth and id be better switching it to negative then getting the neg earth module

 

any advise appreciated

IIRC the positive earth versions are a bit of a workaround, the components inside use negative earth and have to be shielded. Maybe that is where the issue lies. Changing to negative earth not an option?
