Well thank you for your insight Marshall. I guess you and I have a different manual because I have never read that. But thank you so much for pointing it out to me that I've not read the "official" Ford Model A manual. Again thank you for sharing your infinite wisdom.

I have not tried retarding the spark a bit when it is doing it. I will try that though. What in the motor could be making it knock like it is?

My 1929 Tudor runs great at idle and while driving casually. I hear a motor knock when I put the motor under a load like accelerating up a hill and such. Any ideas?

I bought an ARCO temp gauge from Snyders. After installation I figured out that it was reading 60 degrees too low. I called Snyders and they promptly sent me another gauge. The new one didn't work at all. So two gauges in the trash, $49 down the tube and one $17 temp gauge from Harbor...

Any ideas how an armature gets magnetized and goes from charging one day to not charging the next? The new used armature worked as I am back on the road.

I misunderstood the guy when he called. He told me when I went to pick it up that the armature was magnetized. He said when he put it on the growler and held a hacksaw blade to it the blade started jumping. I'm not sure what this means. He put a used armature in my generator and a new...

My generator on my '29 Tudor stopped working the other day. I took it to my local generator shop. A few hrs later I got a call saying that it was ready. The gentleman there said it would be $90 to get my generator. I'm ok with that as long as it works right? My next question was "what was...

I do plan on doing that battery charger test first though.

Tom I have found and read a lot of your stuff online. Thank you for posting all the information. My generator will motor but I do still think that I may have a short in the field coil. I think it's possible that the short is bad enough that it won't gen but just good enough to motor. I think...

Thanks Tom. I'll take a look.

By passing the cutout was the first thing I did. I took the generator off the car and took it apart. Cleaned everything up and sanded the inner magnets and armature. I tested the armature with an ohm meter and it tested good with no short to ground. The field coil tested almost zero...

My 1929 model A generator is not working. It will motor but does not put out any voltage. My question is should I take my generator to a shop and get it rebuilt or should I just buy a new generator? My old generator field coil has shorted to ground somewhere I think. Should I just replace...

Turns out it was in fact the coil and or the condenser. I just replaced both and now the car runs great. There is no hard starting and no more cutting out under a load anymore. Thank you all for the advice and troubleshooting tips.

New coil and new condenser and the car runs good again.

Tom this problem seems to be an intermittent problem. One day it worked well then next day it didn't then the next day it worked again.

I'm fixing to install my new 6v coil and new condenser. I'll post what happens then. All the arrows point to a bad coil/condenser. Seeing as how the both of them together cost less than a steak at Texas Roadhouse, I'm ok with replacing both.

The ammeter was showing wrong because when I was fixing the gas gauge it fell out onto the concrete floor not because there was a discharge. My battery hasn't gone dead at all.

103 yesterday, not today yet.

So I came out to the shed today. All the testing I did yesterday was in the evening and keep in mind it was 103 degrees today. No spark at all. Grounding the points, nothing from the coil. Came out to the shed this morning. It's in the upper 80s temp wise, nice morning. I was fixing to...

I guess the reason for my initial question was why would the coil have voltage constantly. It is just a different setup than all the antique tractors I have worked on. When the ignition switch is off there is no voltage to the coil. I was always under the impression that voltage to the coil...
