Sounds like your E.L dash power supply might need an overhaul. If has
some capacitors in it that are likely bad by now which can cause a voltage drop.
Nine times out of ten all that these E.L dash rebuilders do is replace $5.00
worth of parts in the power supply, which take all of about 15 minutes, and
charge you $200 dollars for the privilage.The unit works basically like a tube
car radio power supply stepping up 12V to several hundred by
converting the 12VDC to a pulsing DC and running it through a transformer,
in other words it's a crude power inverter. I am sure that cleaning the
switch with some alcohol or tuner bath will also help so try that first.

Subject: IML: Vacuum Advance
problem
This week I'm trying to get the 62 presentable
for taking to Chattanooga Friday. Got all 4 power windows to work after
rebuilding two motors and some tlc.
I then drove the car for the first time other
than around the block when I did the trade. It did fine except for a
rough idle and slight stumble off idle.
This morning I decided to do a quick tuneup and
in the process of checking the timing, I realized the vacuum advance was not
working. Could not find a vacuum advance at any local shop but Autozone
had a complete distributor for 38 bucks. Put it in and the car idled
great but pingged like mad Messed with advancing and retarding the
timing, setting dwell, all the tricks I knew. Nothing worked. Push
the gas and it pings and rattles. Messing with it made it better or
worse but nothing made it go away.
So I called the Doctor. (Robert Soule) who told
me the new distributor probably had the wrong vacuum advance unit for the car
and was over advancing the timing. So what have I done?
Disconnected the vacuum advance and set the timing at 16 btdc. It runs
fine but has the same lumpy idle as the old distriubutor
did.
Anyone got any ideas? Where can I get the
correct vacuum advance unit? None of my parts houses show
them.
Also going to have to do some work under the
dash. No power to the fan motors or antenna switch but the antenna
works if you jump 12V direct to the wires. Also the EL dash if
flaky. Nothing on the needles and the guages are dim and the switch has
dead spots. I'm still doing the "Dick Benjamin boogie" and twisting the
knob so perhaps it will break in. I"ve got a spare instrument cluster
and EL transformer. Makes it kind of interesting to drive at night
though.
