I AM LOOKING FOR A DIMMER COIL FOR MY 1918 MODEL T TOURING CAR THAT WAS USED WITH THE COMBO LIGHT/HORN SWITCH WITH MAGNETO LIGHTS. THANKS
I got one for a project maybe 15 years ago and I think it came from Ron Patterson. Hope that helps. Itís a pretty obscure part.
I got mine last winter from Bob's...they had several in stock, both firewall mounted and those mounted to the ammeter blank plate.
I'm new to this forum, I'm restoring a model t from the ground up, who is bob's? Thanks
If you don't find what you need through their website, be sure to call. I don't know anyone there personally, but they're very personable and helpful on the phone.
I echo Jack's comment.
Be sure to call if you don't have pay-pal. Easy peasey.
Keep us in the loop if you would, I should get one also for a Runabout.
Good to see you on here.Tim From Saginaw.
Bob is quite amazing, he has parts that one just wouldn't expect! I was looking for a Radiator shell with patina but no rust out. Bob selected on from his collection, and sent to me. It was not only what I was looking for, IT WAS PERFECT!
Do not forget this guy! Thanks Bob!
Thanks guys for the help! Bob took care of me. Appreciate the information.
Just for your info guys - the dimmer coils came in slightly different styles. Electrically they are ALL THE SAME. The core of the thing was made from Fender scrap. Early on they were mounted to the engine side of the firewall and held there by wood screws fed through the core laminations (flat plates stacked) and a hollow spacer was used with each wood screw. The spacer was in fact the same part number as used on the coil points. Though no mention is made of the effect of the wood screw and spacers it would probably be best to use brass versions of both the screw and spacer since brass does not affect the inductance even though steel screws and spacers probably doesn't have much effect on the coil either but I have never measured one of them carefully to verify that. After introduction and at some time after the dimmer coil began to be used Ford designed a small steel bracket that replaced both spacers. That may have been to make sure the magnetic properties were constant and it may just have been to make installation faster and/or cheaper. The only real difference in dimmer coils is the external tap wire length and the ones with the really short wires were the ones mounted behind the ammeter blocking plate on the "cheap" car.
Hope this helps.
You can also use the "blue tip" bulbs that were for use on the 1915-18 Model Ts. They are for higher voltage. They may still be made, but there are some old stock around.
