I recently got my spark and fuel issues resolved thanks to those on this forum. I am starting a new thread as the topic I am dealing with now is so different and will hopefully help others find this topic. I want to say i have reviewed older post on this topic, but many deal with altered equipment.
Tractor: Ford 1953 NAA with original 6v Pos Ground system.
Issue: There is no charge registering on amp meter on the dash - shows straight up 0 running or not
In order to solve spark issue, i recently replaced the B Type voltage regulator as the old one was fried (guts melted). The part # for the new VR is FAG10505A, which is listed for the NAA and is type B from my understanding. I also put a new 6V battery, new points and condenser and have good continuity on all wiring from the BAT terminal of the VR thru the ignition switch and on to the coil.
I also polarized the VR by removing the FIELD wire from VR and touching to the BAT terminal with the battery hooked up (pos ground). This was the polarizing instructions that came with the VR. I had rewired the tractor a few years ago and at that time ripped all the old out as it was installed wrong according to the wiring diagrams and it did start showing a charge at that time, but that was short lived. When I start the tractor the Amp Meter on the dash stays at zero now. In the past it would sometimes move to the minus range and sometimes it would show a very strong (almost too much) charge reading.
I will be checking for good contacts on all wiring up to the VR this evening by checking continuity and connections...I do have some preliminary questions for the checks to do this evening.
1. I read on a prior post to check the Generator to see if it motors by connecting the battery "hot" (meaning negative post of battery since it's POS ground) to the Field and Armature post of the generator. I am a little unclear on this procedure...I can run a wire from the Neg post of battery to the Generator, but do i split the wire and hook to both the ARM and FLD post on generator at same time???
2. I know the rear most post on the GEN is the ARM, but have no clue with of the remaining 2 post on the barrel of the GEN are Field and Ground. I don't want to assume by the wiring as there is a chance they are not connected to the correct places as I am the one who hooked them up. I will try and clean the GEN surface and look for a stamp unless there is an easy way to tell.
3. I also read on here that there is a difference between a FULL POLARIZATION and doing it at the VR as i have already done. Do I need to POLARIZE at the GEN also by using jump wire from the ARM to the FLD on the generator or is this pointless after having done the polarization at the VR?
I will post what I find this evening or tomorrow morning...if anyone has time to offer guidance on the above or any other procedures I should do, please let me know. I don't want to fry my new shiny VR, Battery or Points though.
Thanks.....Brad
