The post which had Jim's link to the diagrams is part way down the page here, but the links are currently dead. I am sure that Jim will fix the links if he still has the diagrams. If not, then we can cobble something together. I need to make the same mod to my current Xantia V6, as a precaution.

Note that by the time they become intermittent, the contacts in the starter solenoid are already badly eroded, and the relay mod does not always fix them (but it usually does).

The first time I made this modification on a Mk1 V6 is recorded here, there are some hints on diagnosis, but I did not give specific instructions.

Links now fixed ;)

Sorry about that :oops:

Here's the links for easy reference:

Standard V6 Starter Circuit

Modified V6 Starter Circuit with a Helper Relay

Copy of the text from the linked post:
I took the live feed for it from the unused (in my case) Engine Bay fusebox F6 which feeds the headlamp washer timer relay which if fitted sits next door to the start inhibit relay (violet) in the engine bay fuse box.

I carefully removed both the unused washer relay base and the start inhibit relay base from the fuse box by releasing their holding tangs and rotating them a few degrees in their bayonets to release them.

I then carefully prised off the red underside insert on the relay bases to allow the wires, complete with the spades, to be removed from the bases.

I left the wires to pin 5 (supply from F6) and Pin 2 (earth) in place on the washer relay base but removed the wire from pin 4, insulated it and hid it away. The wire to pin 3 I cut to about an inch and a half long. The wire originally to pin 1 I cut about an inch and a half long and removed it from the base to give me a tail with a relay spade connector on the end.

From the start inhibit relay base I removed the wire going to pin 5 and moved it to pin 1 on the washer relay base. I inserted the tail I removed from pin 1 of the washer relay base into pin 5 of the start inhibit relay base and then jointed the ends of the wires from pin 5 of the start inhibit relay base and pin 3 of the washer relay base with a butt crimp.

Refit the red relay base inserts.

Insert a black 25A relay in the washer relay base and job done! Enjoy a reliable starter!

Another mod I did was to do away with the two-pin connector by the aircon pump that carries the starter solenoid feed. It's a single white wire in black curly trunking. I replaced the connector with a butt crimp as the connector is barely up to the job.

If you do have headlamp washers, you'll have to mount another relay base somewhere else but you can still "borrow" a supply from F6 as you won't ever be washing headlamps and starting at the same time!

Just a standard automotive relay Howard. I used a light green relay I appropriated from a scrap Xantia but any standard 20A Automotive one will do...
