Unanswered: No spark at coil during start
Set-up: It is stock start/run set-up... except: push-button/relay activated start solenoid (applied to/in-place-of black/red at column loom). I recently removed an extra coil resistor ballast (by PO) and have enjoyed misfire-free loaded running! I figured the original appearing 35 year old coil must have cooked...(did I just say figured? I meant ASSuMEd)...so here I go! I had new parts at home and began throwing them at it first... and THEN tested the old ones to be "OK" after there was no change. Coil, condenser, verified points ground function & 12v (unloaded) at the coil. I did NOT test solenoid lead independently for 12v out. I noticed with spark tester on coil, I was getting a brief spark flash at depress and release of the button... with coil voltage [dropping] and no spark while cranking. Sooo, I bumped the starter about a half-dozen times this way and cranking spark returned! Great... but I'm not sure what failed and then corrected. I'm strongly considering driving to the Tacoma meet & need to get a handle on this... so Advance Thanks for input!

To bypass (coil power) internal contact in starter solonoid?
...so I'm going with this (from above post).
Thinking about adding a diode to coil 12v lead, and then just tagteam off the starter activation spade with existing start circuit wires. I don't run start current through the ignition switch anymore (pushbutton & relay). Is stock gauge solenoid activation wire adequate to also supply coil draw during start? Advance Thanks! -Dan

Using existing wiring, I have bypassed suspect (intermittent defective/failing) 12v ign. coil contact in starter by tapping-in on activation terminal through installed (6A) "NTE 5815" rectifier/diode.
Appears to be working as intended. This may also eliminate my occasionally experienced need for excessive cranking I've thought caused by vapor lock, cold blooded-ness, flooding and/or evil demons.
