Fitting an X-Charge

I'm fitting an X-charge split charge thingy to my 300 TDI 90 (having removed it from my old 200TDI 110. There is a thin orange wire that attaches to the thinest of the three wires that goes into a plug which pushes into the alternator. Wire colour is brown/yellow. All good as this was what was on the 200 TDI.

However my 300 TDI is diffrent. It has two thin wires going to seperate terminal. One is brown and the other appears to be white/grey. There is also a thick brown wire.

My question is .... which wire does the orange wire attach to? my choice is the thin brown one. Is that right?

Thanks,

Guy

You should be able to check with a voltmeter. One of the thin wires should be at a constant voltage, and the other should vary with the engine rpm. You want the one with the constant voltage.

One of them will be a feed for a tacho (if fitted), this is usually denoted by a 'W' on the back of the alternator if you can see it. Try disconnecting them one at a time with the engine off. Whichever causes the charge light on your dash to extinguish when disconnected is the one you want!

Si,

Thanks for this. I don't have a tacho but I will pull off wires in turn and see what happens. Wiring is not a strong point of mine and I was looking to avoid any unfortunate fires etc etc!!!!

Thanks for the help. I shall poke around tonight.
