Pink and yellow wires...

Post by 56_oval » Fri Jun 01, 2012 2:27 am

I'm sure it's been covered, but I couldn't seem to find a clear answer on the search engine. Can I hook the yellow and pink wires together permanently to keep the stator charging at full power? Or will this cause a problem? I will be using a smaller battery than stock (4Ah) and a solid state rectifier.

Go for a ride with a voltmeter taped on the handlebars and see what you have for voltage.

At the moment, the frame and other bits are at the powder coaters, so it'll be a few weeks before she is on the streets. I am just curious if it's safe to do or not. I don't wan't to burn up the stator or anything else for that matter. I don't know it really matters anyway as I am not using a starter.

It's unlikely you will hurt the stator, too much juice will boil the battery dry and will be hard on light bulbs. British bikes of that era used a zener diode to shunt the excess current to ground. The zener is grounded to the bike via some sort of heat sink and is connected to the battery/regulator output wire. You could use one from a 1979 or later Triumph (negative ground) if necessary.

If ya are concerned about charge voltage get a rotor which has CB72 rather than CB72 (L) and ya will improve the charge voltage.
HONDA changed to the (L) issue to lower the charge as the battery would boil the electrolyte and as the owner wouldn't check the battery it would go bad.
Keep in mind we rode these bikes All The Time in the 60's. ........lm
