Did any cars have 6 volt wiper motors? I thought all the old 6 volt cars had vacuum wipers.I sell a heatsinked dropping resistor to run a 6 volt tube radio or a 6 volt heater fan motor in a 12 volt car. Sold a lot of them, they work good. But I have a customer that wants to use it for a 6 volt wiper motor. I've never heard of a 6 volt wiper motor Thanks
My 52 Ford pickup has 6 volt wipers. 55 DeSoto and Chrysler had 6 volt wipers also. Yes they do exist!!
International pick ups 1946 -1949 and possibly 1941 - 1945 had 6v electric wiper motors. I have one or two if you need any. These fit above the windshield.
The Chrysler and Ford 6v wiper motors are positive ground, while the VW wiper motors are negative ground. This should not affect what your resistor does. Biggest issue is heat, but if you can run heater fan motors you should be able to run wiper motors. It all depends on the current being drawn in worst cases.
I run the original 6 volt wiper motor on my 48 Dodge now on 12 volt, just not too long at a time. The original was two speeds, so now slow is fast and fast is real fast.
Hi. My 46 Chevy Coupe has 6 volt electric wipers. I am the third owner & this was a conversion done by one of the previous owners. The whole key to matching a resistor for voltage drop is the amperage of the motor AND a mounting location where the resistor's heat will not cause problems. Jimmie
Yes, the thing is you would have to find out what current the motor draws, I guess that would change with the load on the motor? And if the current changes with load the, resistor needs would also change. I would think the best thing to do would be to adapt a 12 volt motor.
Chrysler had electric wipers starting in 1940. There were electric wipers before that but Chrysler was the first major company to make them standard equipment. So, they made 6V wipers for 15 years 1940 - 1955.
I bought a 6 volt motor from ebay which was made for a boat, shortened the shaft and adapted it to the cable setp on my wife,s 54 Chevy, worked great.
Indeed. Just for an example, an electric motor draws ALOT of current as it starts (or when loaded so heavy it stalls), and that reduces as the motor rpm goes up (keep the load too high for too long, and the high current will burn it up - but that's beside the point right now). Lets say the motor draws 5 times normal running current at startup. If the resistor is chosen to give the motor 6V (from a 12V source) at normal running conditions, the initial high current will cause a way higher voltage drop over the resistor. That means the motor will not get 6V, probably more like 1-2V. If the motor is able to start and get up to speed that might be okay, but it will be a slow start compared to normal. There is a good chance the motor is unable to start at all, too weak to begin moving at such a low voltage. A motor, and anything else with a changing current draw needs an "active" electronic regulator that produces a steady voltage no matter how low or high load there is. There are plenty of options to solve that, if you just know a little about electronics.
For the person who wanted a link to these resistors I sell, They are Ebay item # 231533919154. I've used a lot of them on tube radios I refurbish and sold a lot of them with never any complaints. It's a simple voltage dropping resistor and I know the amount of voltage it drops depends on the load in series with it. But for tube type car radios and heater fan motors it drops and "uses" about 5 to 7 volts, which is in the ballpark, and works.
Model A Fords used both vacuum and electric wiper motors, 6 volt positive ground. If you tell us what type of car the customer has some other ideas might come up. Charlie Stephens
I've had 4 Model A Coupes, all with 6 volt wiper motors, mounted onto the windshield frame. Also had a bunch of windshield frames with holes for the electric type motor.
my 55 Studebaker had 6V electric wipers. Boy did they go when I converted to 12V then I took the arms off because it was a Custom
Hi everyone, I'm my new to the group and hope this post is not out of line. My 53 has electric wipers (6 vdc) which I've read were a factory option. I was an industrial electrical tech and may have some insight into the question. Compared to a 12 v, a 6 volt motor will flow approximately twice the current so it can produce the same power. The higher current flow is why 6 volt wiring is almost always a larger gauge. A voltage dropping device should not be used with the wipers in a 6 volt circuit. The resister, however, is required in a 12 volt circuit running a 6 volt motor, but in this case it would be better to find a 12 volt motor. As you mention using a voltage dropping resister works well with small loads such as 6v radios in 12v systems. But in larger load circuits the resister creates undesirable heat.
