Re: electronic regulator problem

Simes that sums it up perfectly. Bullets added to the new one to marry up with the existing harness to minimise any intermediate fault. I take it the main body of the unit doesn't need earthing - just the red wire to earth. I bought the unit from Paul Goff via ebay - id have thought it should be oka...

Re: electronic regulator problem

simes with the mechanical reg - slow revs 6.15 up to 7.6 or so at high speed (until it regulates down to about 6.40) With the electronic one attached just around 5.89 running at any speed when revved up, - Battery recovers when the ignition is switched off to about 6.10 but if I went for a ride I'm ...

Re: electronic regulator problem

Dave
Battery is healthy with just over 6 volts showing on a voltmeter. I'm quite sure the problem is elsewhere . I wonder if the ignition light circuit to the red dot ammeter could be the problem (if at all). Might try disconnecting that and giving it another go
thanks for the reply

electronic regulator problem

The mechanical regulator on my square 4 works ok but I decided to go modern and put on a new AO V-REG regulator on I run on 6 v positive earth and the swap over is (should be) simple, however on start up - no power getting through the unit. Ammeter needle is in the middle and the red dot ignition li...

Re: Saddle springs - comfort

Expensive but worth it
I recently rode a pre war Norton inter with those barrel springs - very nice ride and not at all choppy.

Re: partial loss of oil pressure - square 4

You were 100% right Simes! Just took the ball bearing out and cleaned it and kicked the bike over to make oil issue out with any potential obstruction. Replaced the bearing and spring and started her up. 100 PSI on tick over from cold Must have been a bit of muck in the system, or in the oil pipe fe...

partial loss of oil pressure - square 4

Hi all can anyone shed light on the following. After much cursing and time I managed to fit a remote oil filter to my 51 square 4 Immediately prior to fitting it oil pressure was 100psi on tick over when cold and very gradually (5mins or so) would drop to 80psi. After that it would further reduce as...

Re: SQ4 Mis-Fire

Simes difficult to say. Could either be ignition or carburation. Mine has a tendency for the pilot to partially block causing problems at the lower end but usually I can nurse it through to the main jet where the problem will disappear. I also have a volt meter fitted and if travelling at low speeds...

Re: square 4 remote oil filter fitment.

Simes
thanks-I did bend the return pipe about 130 degrees, but I think a length of copper pipe may give me better clearances. I was trying to minimise the joints to reduce the inevitable leaks. I will have another look at it today.
Cheers

Re: Ammeter Repair

I rebuilt my red dot ammeter after my crash 3 years ago - what fun! I had to get an non working britax ammeter from an auto jumble sale and transfer the gubbings from the red dot into the emptied out casings. (with some delicate repair work) I added a bulb for the ignition and it all worked fine - i...
