Allrighty then
I am taking your good advice and going back to 6 V
thanks for all your good advice

Just needs some gentle nudging in the right direction!LOL Seriously, if the mechanic has done good work for you before, keep them and the two of you learn together. I have a small town mechanic, their work ethic is fantastic, they fight over who gets to work on the Packard because as one told me "I can't stand the computer telling me what to do!"LOL The only thing my mechanic can't really tackle is the wiring issue and I have located another that is ready to tackle the issue (I really think they didn't get it grounded solidly, we'll find out) but my mechanic sent a picture to the wiring shop, they are excited to work on it! And I loan them my reproduction repair manual, leaving it in the front seat when I drop the car off! Flexibility is the key. Best of luck!

Keeping it 6V positive Ground would be the best way to go. I have had experience with running an 8 Volt battery. They are a "Poisoned Chalice" and really strain the charging system, particularly if you have a non temperature compensated voltage regulator as all Juniors up to 39 and Seniors prior to 1936, which I would suggest have two coil regulators at best and cut outs before those. I ran the 8V battery in my 38 Richards Six for 3 years and it really gave the charging meter a rough time. On start up it was like you shorted out the Field on the Generator as it went full bore at over 8 volts until the voltage regulator heated up and it went down to 7.5 volts, then it appeared to be ok. In the warm up period you could smell the wiring and it was a disaster waiting to happen. I went back to 6 volts and fitted a higher torque starter motor from the 1950's. The torque ratings vary considerably with the starter motors. I have attached a chart on starter motor torque variations for general Forum information. I note that these later bolt up starters will not fit your 34 but perhaps you could fit a later single bolt starter but I do not have the starter torque ratings for these. Perhaps Dave would know what higher torque starters may be fitted to your 34. I have a 1934 starter motor fitted to my 1928 533 and it works well. Good luck.

thanks again very happy with mechanic, old enough to know about these older cars, young enough to do the work, always open to suggestions
