How to Fix MG Rover Electrical Problems - Pektron Relay Fault - 8/2003 on

Own an MG Rover built after August 2003? Is one of the following not working:
Horn? Drivers electric window? Central Locking? Fog lights? Intermittent wipers?
It is very likely going to be one or several of the Pektron relays in the SCU unit that have gone. The relays are readily available for about £5 each on the web. It can all be fixed in under a day with some soldering tools, sockets, patience and perseverance.
Such a shame one small component, not even made by Rover, have just a detrimental effect on electrical reliability.
Here we fix a 2004 MG ZR but the Pektron relay are also used in the MG ZS, Rover 25 45 and MGF, so the general instructions are also applicable to them. Just the location of the SCU unit will vary.
On the MG ZR with a/c most garages will say the a/c has to be degassed etc (more cost) but here we leave the a/c connected. The SCU unit can just about be wiggled out from behind the a/c evaporator(radiator) unit with it still connected if some of the pipes clamps are loosened.
I wouldn't just replace with the same pektron relays, get the better quality replacement ones. This is where to get them on eBay:

Pop into Amazon or eBay and you'll find people selling soldering irons, solder and solder suckers that are also required for this job. Just searching for those names should give you a lot of sellers. For instance on eBay here are soldering iron stations similar to the one I used:
