Stuart,
Thanks...whatever a full wave bridge rectifier is, we then have one? Glad it's full; I hate to do anything half way.
I had a picture of an International 36 Pumper up on that page for identification (which was done by the Bolters), and then just used that URL in putting up my full half bridge wave rectifier :-).
The truck is a '53 bolt, started as a small paint job and has escalated into a complete resto. I might as well have started with catogues and built up from there. Amazing lessons from this truck.
