Re: Starter motor plastic cover removal
Hi Charles Please see the attached picture. For some reason this did not go through on my original reply. This relay has 2 separate output terminals (87 and 87b.) They are electrically separated when the relay is not energized so the Red/white wire and White/LG wires would not be connected together....

Re: Starter motor plastic cover removal
mgb relay.docx Hi Dave I agree with Vic, BL seems to have made a bit of a meal of this. You could change the starter relay for one with an extra output terminal 87b. Connect the Red/White wire to 87 run a new white/LG from pin 87b to the coil (or find the existing wire in the loom that goes down to...

Re: Starter motor plastic cover removal
Hi Dave Good news .Sorry if my reply was a bit OTT but there has been so much comment on this forum about problems with the car ignition systems on rubber bumper cars, especially around the 12 volt feed terminal (*)to the coil on the solenoid. (*or lack of a terminal on some of the new starter motor...

Re: Starter motor plastic cover removal
Hi Dave Charles description of the wiring /solenoid operation is correct. The white/LG wire has to be on a separate terminal otherwise with the ignition on, the solenoid would be constantly powered from the coil /ballast resistor circuit. Although this may not be enough voltage (6 – 9 volts) to enga...

Re: Overdrive cutting off
Hi
I had a problem with my overdrive dropping in and out. Turned out to be a corroded bullet connector in the harness below the fuse box. The overdrive wiring is the Yellow and yellow/red wire. Pull the bullets apart and clean with wire wool /emery paper.

Re: Starter motor plastic cover removal
Hi Dave I would start by checking out the starter and ignition relays screwed to the inside of the driver’s side wing. Look at the diagram on top of the relay and with the ignition turned on, connect a meter (DC volts) between pin 30 and ground on the ignition relay and check for full battery voltag...

Re: Starter motor plastic cover removal
Hi Dave The starter motor cover is not the easiest to remove. The plastic goes hard with temperature and time. Try using a hairdryer on the cover to make it softer and more pliable. You should then be able to wiggle it off. The wiring to the solenoid is the main feed from the battery then to the res...

Re: MGB GT front Qlight rubbers
Hi Good article Paul. I’m sure this may help answer Grahams question. Unfortunately parts quality is starting to become a major issue. Just ask anyone who has recently fitted new MGB clutch kit! I cannot comment on Rimmer Bros parts, but I do know that most rubber components for the MGB are manufact...

Re: Brakes continually need re-bleeding / reservoir needs topping up
Hello Paul I would agree with Mike. I experienced the same problem a couple of years ago and suffered complete brake failure. Couldn't find any leaks but when I removed the Servo, the main vacuum chamber was full of fluid. A tell-tale sign is white smoke from the exhaust as brake fluid is sucked int...
