I am trying to figure out what I have here. I noticed that there are two different wiper switches available. 70-72 and 73-76.
This is the one that is in the best condition. Notice that it only has four pins on the left side.  I have already attached a switch that I got from davep, which will trigger my electric washer pump that I plan to install.  This is the second one that I have. Being in worse condition out of the two. It has five pins on the left side. The extra one being a brown, which is ground correct?  The switch is also different in that the plunger that would activate the washer fluid has an electrical contact  I am running a wiring harness from a 72 car. Which switch do I need to use? Am i missing pieces from the first switch maybe? Im stumped here... Pete |

I put a 16 amp in and put the wiper switch all the way up, key on, zap! it immediately fried.

QUOTE(Krieger @ Feb 29 2012, 06:55 PM)  I put a 16 amp in and put the wiper switch all the way up, key on, zap! it immediately fried. OK. No more destructive tests for now. I assume that the wipers didn't move at all, correct? take out the connector from the switch and measure the resistance between the wires and ground. here is what you should get: green/white 0 ohm or very low Red/white infinite. black purple will read the motor resistance Black blue should read higher resistance than previous one. If all is good, next the switch will need to come out. If that's not an isstrue, you can take it out now to test the wires as crawling under it is a PITA. |

So I am measuring between the ground terminal on the plug (body harness) that goes into the back of the wiper switch and the other wires on that same plug?
here is what you should get: green/white 0 ohm or very low---dont have a green/white, i have a black/green white Red/white infinite.---red/gey?... black purple will read the motor resistance---dont have Black blue should read higher resistance than previous one.--dont have My wires don't really match your descriptions... |
