dashboard resistors

Ni Chrome - Nickel-chromium wire, freely available in various gauges.

vibrating regulator? enlighten me, please.

The voltage regulator is a big rectangular box, on a different mount from my experience.

On the mk1, according to my wiring diagram, the illustrated item serves two functions. Power comes from the ignition switch (terminal C on the switchboard) to the top of the fuse holder. From there it goes to two places. A jumper runs down from the top terminal of the fuse holder thru the resister and on to the coil. The power from the top terminal also goes thru the fuse and on to the hot terminal of the two gauges.

As a result of this setup, the gauges are protected by a suitable fuse. The coil circuit is not protected.

There is another single fuse box nearby that protects the lighting circuit. I'll try and get some photos later today. In both cases the fuses are a little different in their design, which would seem to allow the repair of them by the user.

I had a google at the part number of 11A-12250, which is what FUC-3 calls for, and it is indeed a breaker and resistor assy like I have always seen on the cmp trucks. I am not certain that part would even fit in the tight confine of the mk1 control panel. It may have been a change up from the earlier control panels as well. My original fuse holder/resistor would appear to have been on this panel for a very very long time.

Post 196 has a couple of pictures off all original resistors and fuse assemblies that came out of a Mk1 dash. I cleaned them up and they worked fine in my carrier.

I have some of these available new old stock. The resistor is the same as used on all Fords of the era, the voltage cut out and this particular installation is part 11A-12250-A. The parts book informs it fits 1941-46 passenger and trucks.
Price is A$40 plus postage.

Your dash appears identical to mine in layout and components. I note the cover on the larger fuse holder is Ford Motor Company marked on the inside of mine. Not sure if Ford merely copied the Lucas part, or if they even had Lucas make them up with Ford's name on them.

T16 resistors, Windsor bits too!

[BCA]

I just measured the resistor on a Mk2 panel: This resistor which stands alone without a fuse block, (unlike the Mk1 resistor which also has a fuse block) measures a bit under 1 Ohm. The trick would be have it in a running carrier and see if the voltage at the coil was about 4.5 ohms. Rob: you said your resistor measures 4 Ohms; chatter on other vintage Ford flathead sites suggest this may be too high and cause the coil to receive too low a voltage. When you get it all assembled and running then test the voltage at the coil and see if it is 4.5 volts.
It would appear that the Windsor Carrier and the T16 Carrier, both being 12 volt vehicles use a "voltage divider": 2 resistors on a mounting block (see Michael R's photo). Two chores are necessary: drop 12 volts to 6 volts for the gauges, and drop 12 volts to 4.5 volts for the coil (assuming the Windsor and T16 coils like 4.5 volts.) I can't prove this theory since the T16 wiring diagram is very poor and I do not have a Windsor wiring diagram.
The resistors on the T16 voltage divider are different: one is about 4.5 ohms and the other is about 6.5 ohms. If they are useful for other applications then I have them in stock..... Brian

I have restored my dash as per the manual wiring diagram and used the original circuit breaker and one of Keith's NOS ignition resistor. I also found a NOS voltage reg, not sure if its a vibrating reg?
