MY KE70'S · by **pervert** » Sat Nov 19, 2005 2:09 pm

I've just noticed on my two KE70's that the coil packs are working differently.

On one, the wire from the distributor to the coil pack is going to the negative side of the coil pack, the other is going to the positive.

I know that it should be going to the negative side according to my Haynes book, so stupidly I tried connecting it to the positive on that car, it got rather hot of course... :lol:

Just wondering why the two are different???

Anyone?

are all the other wires still going to the correct/same terminals on each? -e.g. ignition wire to the positive on the coil?

When you swap them over,

you have to swap all the ones from the 1st side over to the 2nd side
and all the ones from the second side back to the first side.

thats a much better way of putting it then my step by step question plan!

Haha yup, thanks guys, managed to work that one out tonight, I had missed one.

So obviously, the car will run with it set up either way...but the distributor wire SHOULD be going to the negative side of the coil, right?

So if it going to the positive, and the car is running, what kind of problems could this cause? :?:

Basically the coil doesn't care what side you wire things to as long as its all relative. The coil is (as you'd expect) a big coil of wire. You supply it with 12V at one side and the distributor pulses the other side to earth (coil act as a resistor so you're not just shorting a live wire to ground).

If you feed live power to the earth side of the coil and pulse the positive side to earth you're basically doing the same thing.

yeah dosent matter what side

In more modern elec ign coils it does matter as you get a better spark wired correctly,
as it's where the secondary taps off the primary that matters.

Only ever seen one car in at work where it was the problem that it came in for and it was a mid 90's honda ( is that a swear word in here?)
