Re: 1949 - Voltage Regulator takes a couple of minutes to start working

Have you tried polarizing the generator? The generator needs a residual bit of magnetism to start working which is established or reinforced by the polarizing procedure. One of the repair instructions say to repolarize any time something in the generator circuit such as the generator or regulator is worked on, changed or disconnected. It is also possible the regulator is not the correct one for the car. There are positive and negative ground regulators although no one has to the best of my knowledge adequately explained any difference in construction between them vs one that is labeled universal. If yours is the wrong one that might explain what is going on but that is only speculation.
In these 51 instructions from the SM, A terminal is labeled ARMature or GEN on the regulator, B terminal is BAT. With everything hooked up but engine off momentarily use a short jumper wire of 14 or 16ga to short the terminals together. There will be a small spark and the short does not need to be held more than a second or so. Be sure of the terminals used so you DO NOT inadvertently connect anything to the FLD terminal. It may not help if there is a problem with the regulator but done properly the procedure will not hurt anything either.
