sunbeam ser 5 starting/running problems

[haystack]

i need help with my ser 5. its very hard to start.usually the battery will appear to have run down after a few attempts only to then come back to life strong as ever. its like as if it takes time for the charge to buil up again. after i turn off the key the car will often continue to run for a few seconds . the car is also running badly a little spluttery with backfires , lack of power ect. the sparkplugs are ok i think. i suppose that the points are off also.

what i had in mind is instal an electronic ignition system. can anyone recommend a make and model and where id source it?

do i need a new coil and would it solve the problem at starting the engine ? what coil should i buy and where would be a good place to source one


all help appreciated !

From 33 years experience in the repair business, I would say the starter motor is at fault for the slow cranking speed assuming your battery is good and charged but get it checked as I am merely guessing from what you have writtn, the rough ruining could be any number of items, probably best to find a reliable mechanic/ garage (classic friendly) . As from experience trying to diagnose faults via email is costly and time consuming, as your problem could be fuel, ignition, mechanical or a combination of all three.

Check for weak or corroded ground on Battery....Poor ground can cause these problems...as fo ignition...try accuspark....sold on ebya UK

Over here in the UK there are specialist welders who can 'stitch weld' a crack in the engine block and bring it back to life again. Not sure whether you have that facility over the pond, but I would have thought so. Saves looking for a replacement engine/block then.
