windshield wiper motor size / power

Hey

Need to know the power of the wiper motor (in watts) on the 65 Riviera. My resistance for the Hi and

Lo speed are broken and needs to be replaced. I know it is a 20 Ohm but I need to know how many

watts it needs to take.

Anybody who knows those numbers?

Thanks

E/R=I

E=volts

R=resistance ( ohms)

I= current ( amps)

P=E X I

P=power (watts)

12 volts/ 20 ohms= .6 amps

.6amps X 12volts = 7.2 watts

Are you looking at the shop manual? There is a drawing of the circuit it there.

Is the resistor you are going to replace inside the motor housing?

Impressive work by Arnulfo

Thanks rocky. I'm a retired electrician. Learned that stuff as a first year apprentice.

Yes Jim. It is the internal resistance I am about to replace. I have the workshop manual and know that

it is a 20 Ohm resistance but I was confused when I was looking for a new one as the catalog said

for example 20 Ohm / 1,5 w or 20 Ohm / 40 w. Thats why I thought I might need the power output

of the wiper motor but I guess not.

Thanks guys.

So what did you finally install?  I have the same problem, the hi speed resistor is busted.  Am assuming there is a resistor out there that could be used in place of the metal wound ceramic that originally came with it?  Thanks, Mark
