I know that I read this here before but thought I would post my experience any how.

I bought the BW CPS from O,Rieley after reading about it on this forum.

After installing it there was little if any difference in how the truck ran.

Until it rained, then I turned on the wippers and the truck quit running.

With every sweep of the wipper blades the engine would quit and then start up again.

I had the old (Ford) unit with me and had to pull over in the rain and change the CPS.

My wife looked at me like I was stupid.

I have the BW unit in my glove box for a spare but know I can only use it on dry days.

I am looking for a spare to keep in the glove box that I can trust on wet days.

thanks for listening.

 

Thats why when it comes to buying a CPS, I always go to the local Ford dealer and buy OEM ones. Have 2 new ones in the glove box.

 

I recently replaced mine again. I installed a Wells from Autozone. Lifetime warranty. I greased it in the O ring area before installing.

Curious, did the cps you removed have a dry O ring. You could have had a failure because the O ring did not seal the rain water out.

I think everyone needs to carry a packet of lubricant/sealant for the O ring in their glove box as well as a spare cps.

 

I get that a lot too. Next time, just explain that either you've got to change it, or she has to hang out the window and play windshield wiper.


Which o-ring are you referring to? The one that keeps the oil from seeping out from the front cover? Or the rubber bushing looking part that goes on the electrical connector?

Either way, it doesn't matter much. When the engine cuts out with the stroke of the wiper, it's related to the electrical frequency of the wiper motor interfering with the CPS signal. This failure can be duplicated on dry days by running the wipers with no water present.

A lot of folks misdiagnose this and think it's water related because they don't run their wipers when it's dry out. Thanks to FTE and threads like this in the past, the OP knew exactly what his problem was and was able to fix it quickly with his spare.

 

I always find these interesting. I bought a BW CPS for kicks one day and put it in. No problems. I ran it for about 5 months and never had any problems, rain or shine.

 

I believe libricating the O ring (both of them) is the right thing to do.
I have read about frequency issues. My question, isn't the wiper motor continousily running in one direction with attachment(s) to operate the wipers. If the problem only occurs in one direction, how does this cause the frequency change?

Maybe i misread this. If this means the wipers were on the intermittent setting and the truck shut down each time the wipers were in use (wiper motor engaged), i understand your electrical frequency statement. If this is the case, after installing a cps, should each of us place the wiper arms in the non-contact position, start the truck, and turn the wipers on to test for frequency interruption/failure?

 

Just 'cause you can doesn't mean you should...

 

Hehe. Whats $25 here or there. Plus I got a lifetime warranty.

It ran better than the grey Ford one that it replaced, and about the same as the black Ford one that replaced it.

 

The last few CPS's I changed got their o-rings lubed with motor oil off the dip stick. It was convenient and I got to check the oil at the same time.
