1949 F1 226 new pertronix, what gives?
 

Hi Guys,

So I have completed the following work on the 49: mounted manifolds, new gaskets, installed correct rebuilt carb and fuel pump (thanks Ken CT!!!!!), new gas line from pump, and pertronix 6 volt positive ground. The truck is running better than ever but still need to tinker with. My new problem is when trying to start the truck it now wines as if the battery is low.

It never ever did this when I ran the truck with points. Had plenty of cranking power. The only difference is the pertronix. I feel like just going back to points but have spent the 75.00 for this gadget that I thought would upgrade the ignition?

Tripled check timing but its correct??

I have also seen other truck with the same problem.

Any Ideas?????

:-huh:-huh:-huh

Check all your grounds. And are you using thick battery and starter cables with the 6 volt system?

Initial timing a bit too far advanced? I can't hear it, but, it sounds like that's possible.

I am using the same set up that I previously used. It used to start or crank like a champ before pertronix. Thick cables yes.

I will recheck all ground wires and shoot the timing with the light.

Will get to it tomorrow morning so I will post a follow up post then.

Thanks for the tips and keep them coming!!!

Is it possible the Pertronix is "on" all the time and draining the battery? See if the coil is hot.

make sure you hooked up the wires right
I put them in mine and there great!!!

you have to reverse the polarity on the coil
follow the written directions word for word

I had a similar problem after the Pertronix was installed...very slow crank that would sometimes stop during cranking. The generator wasn't working right and was draining the battery. Replaced the gen with a 6v pos ground GM alternator and no problems since.

Thanks guys. I will run down the list and report back tomorrow morning.

Coil is not hot.

Double checked the ground and wiring looks good.

Can anyone share/post their directions (from manual) sheet on timing the H 226????

Thanks

I'm at a loss to understand how the disty change affects the crank speed. Will just listen and learn.

I wonder if your Starter ain't going south on ya.

If initial timing becomes too far advanced, a cylinder can fire early enough to really fight the starter. If it's just right (wrong?), it can spin, buck, and eventually kick the bendix out of place, backfire out the carb, or start. It's a horrible-sounding event. :-hair
Not entirely unlike hot carbon deposits in a high compression engine.

Edit- a key point here would be that the starter would sound perfectly normal until fuel/air meets spark. So, you may get a very brief normal sound, followed by the starter choking because it bit off too much to swallow. It occurs to me that, were this to be the case, simply pushing the starter button without the ignition key switch on would result in a normal spin at full starter speed. This is a simple test that can point the way between starter issues or other issues.
If it still lugs without any spark, do a "starter voltage drop test." This will find starter circuit issues quickly. Having a friend is superb for this test.
I also thought that our local heat could easily kill an aging battery. It's hot here!!

Sorry for not posting a follow up sooner.

My buddy helping me physically figure this thing out was not able to make it. It will have to waite till tomorrow.

Another driving day missed. Sucks!
