I converted to an alternator a couple years ago... I bought a very compact
chrome 'mini' one wire Denso which put out 45 amps ( stock gen. is 30 amps?
). I have now upgraded to a 100 amp version as I worried that my electric
steering pump might draw too much current for it to handle. I made a nice
polished aluminum bracket to mount it in the Tiger. I no longer need it so
if anyone was interested in it for theirs... e-mail me and I'll send some
pics of it mounted...

        I had many problems with my generator charging system until I
converted to an alternator system.
Mostly the points in the voltage regulator would get crapped up and stop
working.   I had to run with the cover off the voltage regulator because for
what ever reason the system would only work for a briefly with it on.   I
also needed the cover off so I could regularly clean and clear the points.
I never truly figured out what was wrong in my system.

        You should check and clean all the connections from the battery to
the starter and all the ground wire at the battery and engine strap.  The
metal plate on the back of the generator has to be bare metal; therefore all
the bolt holes for the generator bracket in the block need to be bare for
the ground path.  Check all the connections on the smaller wires at the
regulator and generator for problems.  You should also check the ignition
switch, starter relay and starter motor for any problems.   Something should
be getting near red hot with over 30 amps pouring through it.

Good luck

If you all recall, I had lots of problems with my charging system on my
recent trip to Texas.  I replaced two voltage regulators and sourced and
rebuilt a generator which failed instantly.

The third voltage regulator worked well with the original generator, until
yesterday.

Here is what is going on.  I turned off the ignition and the amp meter
buried off the scale in the - and the ignition light came on. This is with
the key out of the switch. I quickly turned the ignition back on and started
the engine; amp meter came back to normal range.  Now when I run the car,
the amp meter is indicating an over charge from the generator which is
obviously cause by the voltage regulator.

This is exactly what happened a couple of months ago before the voltage
regulator stopped working.  Could a corroded engine ground strap be causing
this?

I am thinking of going with the solid state voltage regulator to see if that
fixes this ongoing problem.  I do not what to convert to an alternator at
this time.

Any thoughts?
