Tried that - seemed to work Ok, but didn't get the option to add pics from my Samsung phone gallery.??

Well I've sorted the starting problems! I found the resistive wire sticking out of the front part of the loom, adjacent the ignition relay, it's a pink fabric covered single core wire similar to the type of wire found wound on to an electric fire element, it extends from the positive+ on the coil th...

Dave, thanks for the speedy reply. Although my car is 1976 registered it seems to have the later wiring loom connections. As the white ignition supply goes directly (unfused) to power the ignition relay, which feeds the fuel pump, wipers, heater blower and the ballast resistor wire - but not directl...

The starting problems on my 1976 MGB Roadster seem to be down to a faulty Resitive Wire (Balast Resistor). The usual suspects can't supply one, I either have to buy a replacement loom(!) or a TR6 ceramic resistor. I think I'd like to replace the 6v coil with a 12v set up to avoid this non- starting ...

Paul / Vic, Thanks for the speedy replies, much appreciated! Unfortunately, after a full mechanical refurbishment last summer, the Car has stood outside for the last 8months, waiting for the overdrive o ring seals to be replaced, as the car wouldn't reverse or engage overdrive when it got warm. I dr...

I replaced the relay with the 6RA I had recently bought new. Everything seemed fine - I now have an ignition light and circuit, the fuel pump, heater blower and wipers run as normal. I went to try to start the Car and found it would only fire untill I let go of the ignition switch - then it stopped!...

Thanks for the reply.

The old round black can type relay has the markings 30/5 - so I assume any 4 pin 30amp relay would be ok. (If 30 refers to the max amperage?)

In fact I fitted a 20amp Lucas 6RA aluminium can type and it still works ok.

I will endeavour to obtain an OEM one though!

The original round black Ignition Switch Relay has just given up the ghost on my 1976 Roadster, the relay is the one furthest towards the front of the inner Driver's side wing, on my UK Rubber Bumper car. What size or type of replacement would be suitable? Moss seem to stock the black 'round can' OE...

Has anyone installed one of the "upgraded" roller bearing clutch thrust bearings, replacing the OE carbon one? Are they good to use, or do they cause quicker thrust bearing failure? Moss have been selling them for some time - so how did they get over the non-concentricity running of the be...
