Can anyone help Buddysbuddy??

Hi all, I just noticed a post by John in the Gallery section. He is in France at the moment and is having some problems, please see below -

Right, so big problems, and need some help urgently!

On the way to Plymouth, and I developed a missfire. Got onto the ferry and crossed to Roscoff. After about 10 mins driving in france, loads of back firing followed by a loss of power, pulled over and after some digging realised that the coil was fried.

Thankfully had a replacement so changed that along with points and condenser. All good. Drove about 250km towards Le Mans and suddenly same issue!!? Backfire loss of power! Pulled over, and seemed to be same issue, but no spares so time for euro recovery.

An overnight in a hotel and a hire car got us to destination and kids started holiday. Whilst bus in garage for repair.

Turns out my analysis seemed correct and the garage replaced the points, condenser and coil - 200 euros.

I drove up to Le mans today to collect the van, checked before paying, work definately done.

Have driven around 200km from Le Mans to Tours and the same thing has happened again!!!!

Any ideas? What could cause a coil to fry 30times. 2 brand new!?

I am at a loss and running out of money!!!


HELP please!!

Hi!

Sorry to hear you (buddysbuddy) is having grief. A few things i was pondering, would a over voltage condition, such as a dodgy regulator sticking too many volts out cause this, I also remember some cars use to have a resister or resister wire to drop down the voltage when running to 9 volts or suchlike, but have more during cranking IIRC, think my old Escort or Cortina had something along those lines?
Though I think a overcharge would cause other issues such at the battery running hot etc?

How about something like a faulty ignition switch - leaving the coil on all the time, surely that wouldn't do it much good. Easy to check if there is 12v all the time, even when off? a multimeter - or bulb and some wire

Would iffy points gap cause a problem?

Hope you get sorted, and get back ok. Good luck, and best wishes!

Cheers!

Ballast resistor

Make sure there is only one wire on the neg side of the coil that goes down to the points.

I have seen this problem before where wires like the cutoff valve or the choke have been connected to the wrong side of the coil.

Excess voltage can burn out a coil but that kind of voltage would also blow bulbs in the lights and indicators etc.

Bays dont have a ballast resistor coil. In fact any 12 volt coil from any car will work fine.

Cheers dudes, EB coming through yet again.

In a hire car at the moment waiting on a call from my euro recovery, I have asked them to inform me of diagnosis before any repair is completed.

I did ask them to transfer it to where I am (a farmhouse in Limoges) and I'll repair myself, but they are having none of it!

I'll keep you informed of progress.

Cheers
