Is this a NEW dizzy, or one grabbed from another car?
The 1500's came with a Lucas OPUS distributor, which had an amplifier
mounted to the side of the dizzy (big box). Some of these (like in the
first '79 that I bought) were replaced by the newer Lucas electronic
ignition, which had an external amplifier box mounted on the pedal box
under the coil. You can tell of it's an OE Lucas electronic as the dizzy
will have stamped on it "45DE4" for the OPUS and "45DM4" for the newer
type.
If you bought something new from one of the vendors, then the
instructions should tell you if you need an amplifier or not. I would
suspect that anything new would work similar to a Pertronix...
Hope this helps.

So Rich Ball came over last night to bear witness to my hell. After
starting and warming up, when trying to bring the RPMs up, the engine
cuts out. I have replaced EVERYTHING except the coil (which should be
tonite). Rich hollered to his dad who is a mechanic and he suggested
replacing the Lucas electronic distributor. When I installed it, per the
instructions, the wires went directly to the coil. Rich's dad mentioned
an "External amplifier" that is required for the Lucas ($400+ at MO$$
and VB). He also mentioned some possible magnetic interference from the
alternator.
I have a couple of questions...
1. does the Lucas electronic distributor REQUIRE the external amplifier
on the 1275? The car never had one before and it was running at one
point (although it was on 2.5 cylinders)
2. does anyone in the Seattle/Everett area have a spare distributor I
could borrow to troubleshoot this?
things done so far:
Confirmed fuel pressure
Installed fuel regulator (Weber carb) and dialed to 3lbs (Holley
regulator, not the junk one, BillL)
Replace fuel line
New distributor, cap, rotor, wires, plugs (gapped to .029)
New fuel filter
Timing was set (but it is questionable given the suspected distributor
issue)
Carb rebuilt a couple of times (all jetting is per the manual)
Float level verified per the manual
And just about everything else!
I appreciate you guys! Thanks to Rich for coming over to check my
sanity.
