Has it always  done this...or just started?

Power is feeding back from the reglators "exciter wire"......normally on an 
"accessory"  circuit....back to the ignition circuit..

Just add a cheap 5 watt  Radio Shack type diode in that wire....   Something 
may have changed in your Alt .or Reg.  to cause this to start happening, if 
it didn't originally....but if it's charging correctly..... add the diode. 
imo

I say it's just personal preference.......I've heard of driveability 
problems without it....but most likely there is a good technical rational 
behind it......just doesn't apply to ALL  Vair Turbo's engines....all 
cams....etc..

I removed mine....run just Pressure retard..with recurved mechanical 
advance, and a knock sensor....but it ran fine at 30 deg. BTDC  at 
idle...with the Dale unit, without the switch..
