Re: [T3] 6V to 12V change


Most opinion with a 6V to 12V change is that the starter will work
OK without needing to be changed.  As it's a motor, it generates a
voltage in the reverse direction to that applied, and the windings
are very robust anyway.   Resistance in the wires will also limit
the current (voltage drop can be useful!).
Some people find the solenoid gives up sooner than normal due to the
bigger current it is switching.

The right way to convert is to go the whole way, with 12V flywheel
and clearancing for it in the bell-housing, but if you decide to go
the whole way, another trick employed is to use the 12V flywheel to
mill the soft magnesium alloy to size; there's (apparently) not much
to remove, plus a bit of wobble to give clearance.  Don't do this
under power or the magnesium shavings could catch fire!  There's a
bit of technique needed, and I would be inclined to use a 'spare'
flywheel myself.

I'm just reporting what many others on RAMVA newsgroup report; maybe
all of them were Beetle or Bus conversions.
