Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

17 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Question as per title really, my other half has left the MX-5 parked in town with the lights on and battery is completely dead. Is it ok to jump the MX-5 from my Cayman?

POST 2Original post

No, there will be a nuclear disaster and we will all have to find a new country to live in due to the UK being radioactively contaminated for the next 3,565 years (give or take a few years). Can you warn us if you are going to jump start the MX5 so we can all buy a flight to Australia. HTH

POST 3 / ORIGINAL POSTEROriginal post

do you know what, I wish I hadn't asked this question about 1 minute after I asked it. I deserve everything I get....

POST 5 / ORIGINAL POSTEROriginal post

its ok, I took the relevant precautions

POST 6Original post

I don't jump start anything unless there is absolutely no other option. I would rather remove the battery and charge it up than risk a jump start. We have seen the after affects in the workshop when a car has been jump started. Blown ECU's and body control modules are possible. We always advise against jump starting cars to our customers.

I'm not having a go I am genuinely interested but what is the problem and what causes these issues. I have jump started dozens of cars, admittedly most of them were many years ago in my teens, with no problems.

POST 8Original post

It would seem to be voltage spikes when connecting leads and from the alternator when the vehicle is started. We had a poor chap in about 8-9 months ago who had just brought a Peugeot. He thought he would give it a clean and had the radio on which flattened the battery. He then jump stated it and blow both engine ECU and a BSI. The repair cost was more than the value of the car

POST 9Original post

Yep. Wholly agree. Not CAN you but DO YOU WANT to. Too many electronic modules nowadays. If you attach/detach the cables in the wrong order or use the wrong hands for each polarity the chances of frying something increase. The good old days with sparks and the occasional flame were much better. Fuses? On a car?......

POST 10Original post

I'm not saying don't do it if you really want to. Just be aware there is a risk. It's not as uncommon as you might think. Also I believe the AA and RAC have stopped doing it in some cases. At the end of the day its your car and you have to way up the risks involved but do it with eyes wide open.
