I installed the 6vdc positive ground alternator using the original pulley and fan which I removed from the generator.? In order to make this setup functional I had to extend the alternator shaft to accept the oddly shaped pulley and fan assembly.? ?There were no original components harmed or altered in any way by this modification and can easily be restored back to original.
In the meantime I will be able to enjoy my old car without worrying about charging issues.? ?I was also able to repair the original horn assembly and remove the secondary 12 volt battery and horn button that the previous owner installed to operate his modern horn and electric fuel pump.? The fuel pump is still installed.? I am using a 6vdc positive ground converter to 12 vdc negative ground.? It works great and provides 12 vdc negative ground with an available load capacity of 7.5 amps.(https://www.plymouthowners.club/talk/proxy.php?request=http%3A%2F%2Fwww.chetscoins.com%2F1929%2Fimages%2FAlternator01.jpg&hash=4eddc5d681f2a6eadd139eb7c83d78b8a4989925)
Looks good Chet. Nice work.

Chet:
Installation looks very good. In addition to the alternator - a much needed improvement - has anyone thought of, or have experience, plumbing in an auxiliary water pump? I just don't like to rely on a thermosyphon system in hot weather and in slow driving such as in a parade.

Brian,
I think the good news is that the chances of over heating in the winter would be relatively low.? I remember from my Army days we had a gasoline heater in the front of the APC.? ?If you were to venture out in the winter maybe a small propane tent heater could do the trick.
As far as parades go I live a ? mile from work and on nice days I plan on driving the 29 to and fro.? The fastest road on my route has a speed limit of 45 mph.? Besides, my neighbor drives his 29 Model A Ford around all the time.? I think I would like to show him what a Plymouth can do.
I think this car still has a number of fun years left to go before it retires to the museum life. Imagine that.., a 1929 part time daily driver.
Chet?
Hi Chet, The thermo syphon system works well on 28 & 29. I have a restored 28 coupe and I use to worry about it splashing out of the cap all the time and I felt it was boiling the water out. I have had it in many parades and use it on the 4 cylinder tours. The trick I have found out is that once it spills over a couple times it finds its own water height and then runs cool and doesn't boil over anymore. Haven't had a problem with it for years. I don't think it hurts it. I have old farm tractors from the 40's and they have thermo syphon and they run out in the field all day and run cool. Just an input to your question on thermo syphon. Bill

Good info.., Bill
I keep filling it to the brim and it keeps boiling a little out. I think I will use your advice and let it find its own level. One question should the cap be an air tight seal. My cap needs a gasket.
Hi Chet, I used to fill it up to the top and it would always boil out. Now after it finds its own level it hardly every comes out and the radiator is cool at the midway to the bottom. The water comes out of the engine at the top and flows to the bottom. The fan and air cools the water by the time it gets to the bottom to go into the bottom of the block. The cap doesn't matter if it is air tight. The radiator has a vent tube and the engine does not create any pressure like the newer cars. Only a car with a pump creates pressure. Still don't take a cap off a hot radiator.
