I have a seies 2, 2000 sc auto that now has a 2.2 engine. I want to fit a new distributor and coil all for electronic ignition so I need to by pass the balast, so where is the best and easiest position to pick up a 12 v supply The car has the original strip speedo.


Regards

When I did this, I removed the gauge pod and wired in the new wire where the ballast wire connects to the original loom. If you run the feed from another 12v source (ie washer bottle) it will be running through a different fuse. Any fault with that circuit that blows the fuse and the car will stop!

I recently helped another forum member in Cyprus to do just this job. The easiest place to bypass the ballast resistor is to run a new wire from the top of fuse 19/20 all the way to the coil. Fuse 19/20 should have 2 white wires coming off the top, one thick (going to the ignition switch) and one thin (which contains the ballast resistor). You need to leave the existing wires in place though as they supply other items. Splice into the thin white wire and solder the new wire onto it. Put a bit of heatshink tubing over the joint and route it down the existing cable loom to the coil.

Hope that helps

thanks for that ,
I have looked at the wiring diagram and totaly agree. On the diagram it is item 73 and I noted that there appears to be a spare terminal in thr loom item 33, It would be good to know where this is rather than cutting and shutting wires.


Thanks again john

Hello Dave,

raylish (Cyprus) here. I did as you instructed and my ignition circuit has worked perfectly since then.

However, I subsequently had my engine out for rebuild, and I have recently refitted it to the car. I tried to do a compression test, but the wire melted all the way from the splice at the top of fuse 19/20 to the coil, with a deal of very worrying smoke!

Any ideas, please? Also, how do you remove the white wires from the fuse holder at the top of fuse 19/20 - I need to replace the damaged wire, but the damage goes all the way to the holder?

Best regards,

Ray
