I have not. Just taking my time to get it
right. The underhood wiring was a trainwreck so I had to
pretty much gut it and start with the wires (Hot-during-Start
and Hot-in-Run) feeding either side of the now-gone ballast
resistor and hence I noticed the low voltage during cranking
on the hot-during-Start feed. (This is the wire that on
original equipment circuitry, bypasses the ballast resistor so
as to give full voltage during cranking.) Ironically, this is
the one reading less than optimal voltage but that same
voltage is prevalent throughout the starting circuit, like I
said, even from battery post to battery post during cranking.
This is turning out to be one of those
projects that’s akin to peeling an onion. It never ceases to
amaze me how over the last 50+ years not one of the persons
working on a particular car had any wiring skills. Sorry.
Rant over. Peet peeve, though!
Thank you,
Jim
Yes, it would be pointless. Just throwing it out there. Have
you actually tried the injection out yet? How does it start
and run?

Hi Mike,
I thought about doing that but let’s
unpack this a bit more:
- The Sniper
wiring has heavy red and black leads that are to be
connected directly to the battery. I believe the little
(14 gauge) yellow wire to be connected to the “clean 12v”
is merely triggering a relay within the Sniper harness
(there are a few built in it; one to power the fuel pump
and another which I assume powers the ignition). If I add
a relay before the yellow wire isn’t that merely
“stacking” relays?
- If the
cranking voltage is 11 volts, in the end there will be no
more than 11 volts fed through a relay, anyway (during
cranking), right?
Appreciate your guidance,
Jim
Jim,
Add a relay to feed the sniper. Tap the starter relay for
power and trigger the relay with the old ballast resistor
output (gut the resistor and rewire). That will get power
during and after cranking.

Indeed, Doug and Mike, those were my
immediate suspicions. Oddly enough, after chasing this
a bit I went to basics and tested voltage drop straight
across the battery terminals and my cranking voltage is
only 11 volts with two different known good batteries.
Hmmm.
Now I’m not sure I have a problem, to
be honest, other than this journey started with,
according to Holley, the need for “a clean 12 volt
ignition feed during both crank and run.”
I’m converting a 440 to Holley Sniper
EFI (including Hyperspark ignition management), and in
addition to feeding the EFI controller, the 12v ignition
feed triggers the ignition module.
I think I’m just going to attempt
living with this cranking voltage and hoping it’s
sufficient for startup, knowing I have 12.6 volts during
Run.
I’ll report back if interested.
most electrical problems are a
bad ground
As
always, check the bulkhead connections.

Thanks
Neal. Got it.
Now
if I can just figure out why I am
only seeing 10.5 volts during
cranking I will be good :-D

would you please send or
