You have K series click. Happens when hot. relay clicks and nothing else happens. My method of fitting the relay (worked fine for 15 years):- It will cost about £10 or £12 in bits and take about 45 or so minutes to fit. You’ll need :- A 30 amp 4 pin relay – available from virtually all motor accessory shops at around £6. A couple of lengths of wire – suggest about 1 foot of black and about 3 feet of red. An in line fuse – preferably waterproof. Electrical terminals – 2 ring type to fit the battery terminals, and 4 female spade terminals (3 to fit the relay and 1 to fit the starter solenoid), although I understand some solenoids are fitted with a ring terminal also – please check. Method:- First disconnect the battery. You should disconnect the negative (Black) lead first. You will normally need a couple of either 10mm or 11mm spanners. Attach the relay to the ‘ledge’ in front of the battery in the centre i.e. around middle of battery. The relay is attached using a tag with a hole in it, which is normally fitted to or supplied with the relay. I prefer to fix using a pop rivet, but you can use a self-tapping screw or a small nut and bolt if you don’t have a pop rivet gun. Detach the smaller wire (i.e. NOT the big red one) from the rear of the solenoid on the starter. It may be stiff, but should just pull off. Reconnect this wire to the terminal on the relay marked 86. Connect a long red wire to the terminal on the solenoid (where you previously removed the wire – see 3 above) and connect the other end to terminal on relay marked 87. Connect the wire with the in line fuse to terminal 30 on the relay and the other end to the positive terminal of the battery (using a ring terminal) along with the wire(s) that you originally removed. ****** It is important to reconnect the positive terminal first ****** Using the short length of black wire connect terminal 85 of the relay to the negative terminal of the battery along with the wire(s) that you originally removed. Check that all connections are secure and “tidy up” the wires using tape or cable ties, making sure that wires are kept well away from the exhaust. Your car should now be ready for use. Start in the normal manner, but don’t forget that you’ll probably have to reset the immobiliser after disconnecting the battery. This is normally achieved by pressing the ‘plip’ about 4 or 5 times – I’m sure you’re all familiar. One other thing you might need (if you have eyesight like me) is a magnifying glass – the markings on the relays tend to be very, very small!!
