MS1 Magneto

Forums

Hi all..

I have a Lucas MS1 magneto on my 1936 Model 18 and need to replace the HT lead.. The lead is stuck in the pick up housing and I don't want to force it too much as I can't find a replacement pick up housing. It looks different to the one's available for other magnetos of the period. Any ideas where I might source one? I attach a photo of the existing..

Thanks

1959 Dominator 99 rewire

Forums

Hi

I wonder if anyone can help with my rewire problems please.

The bike was a just-about runner and I'm slowly working my way through a long list of issues the next of which is the electrics. 

The bike is a magneto ignition and I got it running without the battery or any electrics. 

I've got the heavy twin manual and am referring to the wiring diagram "for 650 Std and de Luxe, 99 std, de Luxe and SS, 88 Std and de Luxe". 

My specific problems are;

3 phase alternator upgrade

Forums

Hi

 

My Norton Commando MK3 alternator has failed. I have taken the opportunity to upgrade this to a 3 phase alternator and associated regulator/rectifier

The new alternator has 3 wires rather than 2 so I need an extra cable from the regulator/rectifier to the alternator.

Stop light blowing fuse

Forums

Afternoon folks,

I hope everybody is safe and well and coping with this house arrest.

I have a 1958 Dominator "99" still on 6 volt electrics. The electrics work except that when I press the brake light switch it blows the fuse, I have tested this twice and each time the same result - a blown fuse.

Can somebody tell me where to look first to see how I can fix this fault?

Many thanks,

Ride safe ( when we are released).

Cheers Mick

questions Norton ES2 (1955) wiring & running

Forums

My dad's trying to get his bike running properly. 

It starts.. runs.. then stops. Like it's using up only the fuel in the pipe.

Turns the petrol taps on.

Pressed tickler and petrol seems to run out the bell mouth and not the tickler... Why's that?

 

Then he's unsure how the head lamp should be wired up as he's had it off and on... Like an earth issue.

He removed the lamp and found some wires loose and two nuts trapped in the bottom of the park light.

He's put the earth back but wants to know about the others.

 

Which battery

Forums

I have a Norton model 50 single, 1957; could anybody advise the correct battery for this bike and a serial number?  I’ve been told that it hasn’t been converted and that it’s a 6volt large. This is all I know. Many thanks

Dave 

Mo1 Magdyno conversion

Forums

Hi, my 1954 ES2 has a faulty Magneto. MO1 Lucas.

i am thinking of updating to a 6 volt Coil system.

can anyone recommend a conversion kit?

i am looking at a Thorspark unit. Has anyone fitted one of these ?

i fitted a Coil to my Vincent Comet many years ago and it transformed the starting and running.

many thanks,

Pete.

Lost dynamo screw

Forums

Hi Guys - in making good use of the lock down I turned my tender mercies to the magdyno. In refitting it all I found the screw which holds the commuter end cap onto the dynamo, missing.

Does anyone have any idea of its details; length, type, TPI?

The dynamo is type E3LM-LO on a '55 ES2. The end cap part no. is 200826.

Bloody annoying - it's those Garage Gremlins again!

George
