Coil voltage

[Giles]

Hi - my car is still driving me nuts!!

Still got the same problem. I have just checked the voltage from the coil + terminal and I am getting 11.8v with the ignition on engine not running (12.4 across the battery terminals) so full battery voltage.

Should it not be about 6volts? Its a mark2 so there is no ballast resistor. I am wondering if the ballast resister in the wiring has gone wrong and fried the coil. As the new coil I got was for a stag that would be six volt as well so that may be also fried??

Only found it when I saw that the neutronic ignition takes its power from the + side of the coil and thought that might be the problem?

Any suggestions gratefully received

Am getting desperate now - was about to order a Lumenition.

sorry everyone

in my delirious excitement - thinking I had found the problem I did not search for previous posts!

Having had a look I found one from seaside bill - it would appear that you have earth out the negative terminal of the coil and then the voltage drops to about 6 volts - mine does so no problem there

However I assume that the neutronic is only getting 6 volts? I have no instructions as it was fitted before I got the car. I assume the white wire is the power and should be 12 volts? Blue is a earth and yellow the feed to the - ve terminal of the coil??

If however if it was the problem it would not be intermittent and it was running Ok so I assume it is not that either.

Hi Giles

I have Newtronic on my PI and mine is wired as follows: white to a live supply (the inertia switch), blue to earth and yellow to the coil.

Hope this helps

Thanks Brian

will wire mine up the same way and hope that cures it. If not will have to get a Lumenition as I am running out of ideas!!!

Hi Giles

The Pertronix unit is good and very discreet. I have one fitted to my Stag.
