Anyone in Sacramento, CA know about installing heater bypass?

[StanAE86]

I picked up a heater bypass tube and was hoping someone in the area has some experience with wiring up the resistors, etc., and might be willing to lend a guiding hand? It would be most appreciated.

I am aware of this page, but don't see the photographic details I was hoping for:

Thanks.

Stan - I'm in Petaluma. A bit swamped to come by, but available by phone to walk you through what I've done.

There is a guy in Sacramento that makes them in carbon fiber (Thom Fitzpatrick). If you need help you could try him. It is very easy though. Simply leave all the stuff connected and either cut into the bypass pipe to insert the sensor or cable tie it up and secure it to something.

Thanks Don and Tom. I have Thom's pipe in carbon. I haven't taken a close look at it yet. But only recall a spot for the vacuum tubes and not the sensor. So, I can just leave the sensor connected, but hanging there and not installed into the tube itself?

As you can see from the picture from the link above:



There are three things:
1) Resistor to simulate the fan
2) Resistor to replace the temp sensor
3) The existing fan motor short bypass

So no sensor goes in the CF tube. In mine, I did install #3 back into the tube, or you could put it in a box as above.

It's #2 and #3 that aren't entirely clear to me based on the picture.

Here is another thread at Rennlist, but it's still not entirely clear to me. I'll wait until I get the resistors and see if it becomes more clear to me.

Thanks!

For number two, you take the temp sensor out, and replace it with the smaller resistor. It tricks the ccu into thinking the temp is about 40F. In the picture you are seeing the electrical connector that plugs into the temp sensor. The resistor is just plugged into the connector.

For number three, you use it as it was originally used. It's designed to shunt off current if the fan motor breaks. I'm guessing you could simply bypass it as well.
