Re: Stainless wheel-nuts for Minators

Hi
If the wheel nuts are standard MGB ones then a spark plug spanner socket from a socket set will fit and might help avoid damaging the wheels. It is longer so fits all the way on the nut so helps avoid damage to the nut.

Re: Ignition light comes on when there is no key in the switch

Hi Charles Totally agree with your comments. I’m sure that many of the problems are caused by PO’s messing with wiring and that if the car in question was physically in front of us, any problems could be easily identified. MGB electrics are rudimentary so electrical problems should be fairly easy to...

Re: Ignition light comes on when there is no key in the switch

There is also a link on the MGB REGISTER web page to electical diagrams. Tech tips - Electrical tips then scroll down to the bottom of the page and click on electrical diagrams. The diagrams are in colour so do help tracing where the wires go. i think if i owned a RB car , given all the postings on ...

Re: Ignition light comes on when there is no key in the switch

Hi Beech Separating the two white green wires will help with solving the problem. I think your problem is with the white green wire coming from the starter motor. Firstly just to explain. Your car is fitted with a 6 volt coil, supposedly to aid cold starting. During normal running conditions, with t...

Re: Ignition light comes on when there is no key in the switch

Hello Beech I would agree with Vic, Charles and Chris in that I think your problem is with the Run relay. Try disconnecting the White / Brown wire, connected to either pin 87 or 30/51 depending on how it has been wired. This is the main feed to the fuse box when the ignition is turned on, providing ...

Re: Aerial on wing

Hi Chris I'm not aware there is a standard dimension for this. I would suggest drilling the hole somewhere between the door and inner front wing splash panel. This will allow the Aerial to retract into the wing void behind the splash panel. Might be worth removing the splash panel to get a better id...

Re: Inlet manifolds

Hi Just measured the original exhaust manifold from my 74 B with a Vernier caliper. The average, after measuring across all flanges is 12 mm or 0.47”. 15/32” (According to my Zeus tables). I can’t measure the inlet manifold as its fitted to the car with a 3 branch manifold but would assume the flang...

Re: Odd engine number

Hi Paul Looked through all my books but can’t find an 18U engine listed for an MGB. As you mention, is it possible the V has been mistaken for a U? As Vic states the 18V780 was fitted to early rubber bumper cars and built to ECE 15 emissions regulation with HIF carbs, AAU needles and 25D Distributor...
