1947 Ford Coupe wiper conversion
I want to convert my wipers from vacuum to electric 12V using the original mechanism. Has anybody done this? I have not looked under the dash yet to see what is involved because the car is out for upholstery. I would like to get on the project as soon as it gets back. Any help or instructions would be welcome. Thanks

Re: 1947 Ford Coupe wiper conversion
Newport Engineering makes a nice electric wiper kit for the early Fords. I have one in my 48. Works very nice.

Re: 1947 Ford Coupe wiper conversion
What has to be removed to access the motor? Radio? Glove box? Instruments?
Or can it just be reached from under the dash? |

Re: 1947 Ford Coupe wiper conversion
I plan to use Newport conversion in my 46. I think maybe you can't use the Cowl Vent if you use their conversion. Maybe paul2748 can answer that.

This is one of the projects that it is better to remove the front seat to install. I installed mine 20 some odd years ago and don't remember if I had any problems.

Re: 1947 Ford Coupe wiper conversion
AS far as the controls for the wiper, Newport has a adapter that can be used with the stock knob, but I'm not sure that applies to a 47 knob. I have aftermarket knobs in my 48 so I didn't have any problem. I do have the adapter in my 54 and 56 Bird and it works. Call Newport and ask them about it.

Re: 1947 Ford Coupe wiper conversion
I made the mistake of getting an electric wiper conversion kit from Bob Drake. I had to cut the support bracket down so that it would clear the cowl vent and it parked with the wipers against the center of the windshield instead of down at the cowl. Multiple calls to them for help were useless. They sent me a diagram to fix the parking issue, and that was also useless. I finally fixed it by taking the cover off and re-clocking the gears by trial and error. Now it parks and sweeps correctly. As far as the switch goes, I'm going to rig it so mine fits in where the original throttle went. My plan is to use a replacement knob with the T on it and mate it to the switch that came with the wiper kit. I did buy a switch shaft extension from Newport, but I still couldn't figure out how to make the switch work in the original location. I just put a replacement dummy control in the original location.

Re: 1947 Ford Coupe wiper conversion
I had to reverse the arms on my crank arm as well. They now park at the outer side and work ok but not great. Minimally effective at wiping, at best.

Re: 1947 Ford Coupe wiper conversion
By the way, my car is a '48 Tudor and has no radio at present, so I don't know how much interference there would be. The cowl vent works fine, however with no changes.

Re: 1947 Ford Coupe wiper conversion
Thanks for the photos, Ritzy1. The first one shows me that I can get access if I remove the radio and speaker bezel. That really helps, thanks!

Re: 1947 Ford Coupe wiper conversion
I used a Vintique 12V motor on my '41. Vent operated OK but the motor immediately quit. They replaced it but it parked wrong. They told me how to correct the park position. I hated it! It squeaked, was noisy and had different sweeps side to side. Talked to a Vintique rep at the NSRA show in Louisville and I told him I thought the "rocker" arm on the motor was shaped wrong. He said no way but offered no fix. Finally I reinstalled my vac. motor and sweeps were correct so I knew it was a problem with the electric motor. I got a 12V motor from a junk yard(Honda), mounted it behind the glove box, ran a linkage from the 12V motor to my vac. motor with no guts and problem solved. Silent, full sweeps, parked correctly and it cort about $10 !

Re: 1947 Ford Coupe wiper conversion
My '47 coupe came converted (12V and motor). They had to discard the stock radio guts, cut away the back of the radio box, and discard the speaker. That kept the front of the stock radio in the dash. I installed a small AM-FM radio in the glove compartment with speaker underneath.
I adapted the motor's electric switch to the stock vacuum wiper switch, so one can't tell the difference. If you'd like some how-to photos PM me. |
