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

I've been following this debate with interest and some bewilderment🤔🤔!! I 'm just pleased I have one of the simpler Bs (1972), I find the electrics on that challenging enough!!! Ian F I' m bewildered too Ian. Poring over wiring diagrams with a magnifying glass tracing wires requires a lot of concen...

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

Hi Vic, Further to my last post i have checked the number stamped on the end of the coil & it is 16C6 which is the ballasted coil. This was on the car which i have owned from new. It confirms the error in the BL ROM ! Cheers, Charles Thanks Charles.. I have a Repair Operations Manual for 1978 B...

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

Sorry Beech, my brain is becoming addled with poring over wiring diagrams with a magnifying glass tracing wires. Thanks for the correction Charles. Charles, as far as you know does your MG still have the original coil? I was wondering if there is anything written on it to identify the type. Mine doe...

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

Not Anumber, are you able to remove the cover from the starter motor to see what wires go where on the solenoid? I know it's an awkward job but it could possibly throw a light on this intriguing mystery you've presented to us.

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

I suppose time will tell, assuming the coil is still 6v. It's an unusual problem to which I don't have a logical answer. In theory with the direct feed from the starter motor disconnected at the coil it shouldn't start at all. Mind you, we are assuming that's the wire that's disconnected as there's ...

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

The fuse holder where the green wire is at the front connects the radiator fan supply via the Otter switch to the fusebox. Green to the switch and fan, white/brown to the fuse holder. The other one the white/brown wire comes in at the front. This wire goes to the ignition coil via the resistive wire...

Re: Electronic Ignition, yes or no?

My 123 turned out to be faulty but something I heard about them is that they do not provide enough vacuum advance for low compression engines. The Land Rover is 8:1. Fitting a spare distributor with points and condenser restored the power.

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

I was about to reply after looking at the wiring diagram but Charles has said what I was going to say. Just one thought. The starter motor solenoid has 3 lightweight wires to it. One is the white/light green 12v feed to the coil, the brown one goes to the light switch and the white/red to the starte...

Re: Electronic Ignition, yes or no?

I can get my Land Rover engine with Petronix to tick over so slowly the ignition light comes on. It's very smooth even at that speed.

Look at the technical thread started 23(?)October 2020 ,on refitting the loom etc (started by me). second page where Vic gives details of the wiring/ terminals of the two relays.
Cheers,
Charles
I'd forgotten about that Charles. It seems so long ago now.
