When I converted to an alternator system I used a 60s style
alternator and built my own bracket. A different alternator would require
changing dimensions of that bracket to make your alternator fit and line up
correctly.
Some of the Ford alternator pulleys have a spacer on the alternator shaft.
Is this possible for your alternator?
Unfortunately you never know when Factory tolerances will stack up against
you and when you change parts it happens more often.
I believe the offset fan belts will tolerate is about 1/8" per foot of
distance. A fan belt web site should list that information to check my
statement. I personally prefer as little offset as possible.
I would not expect the white wire to smoke unless the ballast resistor
shorted to ground but you also need to check the white/blue wire for a
problem.

Subject: [Tigers] Pulley Line-up
My Tiger with a 289 needed a new water pump, so I got the one from Sunbeam
Specialties. No surprises there. Pulley lined up perfectly with the balancer
pulley.
My generator was still ok, but I estimated its life would not be too much
longer. So for a while I thought about swapping it for an alternator. It
never really lined up perfectly. But during 20 years, never gave a problem
either. Possibly shortened the water pumps life? .
Since there was recently a discussion about alternators, I decide to take
the plunge and make it easy on myself and I bought the Powermaster unit. My
alternator pulley is off by > with the water pump pulley! The way its
pulley is mounted it has a heavy rim on the outside, which throws the
v-groove off by maybe 1/8. So if I turn it around, I will still be off by
>-1/8= 5/8. All powermaster other mounting dimensions are identical, 6
between the ears, to straddle the original mounting arm. Now I suspect the
original mounting bracket. 1). I could put spacer between it and the engine
block, the bring the alternator forwards. However the dipstick doesnt give
me much room. 2). I could bring the alternator forwards by putting the rear
ear on the front side of the bracket and add a spacer at the front ear. But
the alternator ear would not clear the rib of the cast Tiger mounting
bracket. Not an elegant solution. But then, how could the original cast
Tiger bracket be off by that much? If it was fabricated it possibly could
bend, but not a casting. Reyer and I measured everything again tonight, but
we can not see whats wrong. Any ideas?
Just one more thing besides my electrical problem: the white wire from
ignition switch to tach to coil resistor filled itself with Lucas smoke.
Why?? All insulation half burned. No obvious short I could see. I am almost
ready to take it all apart and rewire the whole car. Any body has any
ideas?? thanks, Robert Jaarsma
