Wiring to close too backdated heater

[Wout_RS]

Hi Guys,

I've succesfully completed my backdated heating on my SC.
Just got a question regarding the green wire that's laying over the heater duct.

Can the wire get burned by the heat of the duct?
Just did a small block of 10 miles and the duct already feel very hot!
I don't know if the wire was already blackened before or if it was from the heat?



What do you guys do with the wires?


thanks!

This is what it looked like on my SC

If it is working correctly it shouldn't get hot except from heatsoak when the engine is turned off. The hose has a constant supply of cool air forced through it from the engine fan even when the heater is off. (The heater is "turned off" by dumping the hot air air under the car.)

If you don't have air flowing through the duct constantly there is a problem and the heat rising from the heat exchangers will toast any non metal components in that area.

The green wire should go under the hose/duct.

The red wire looks ok, but if it was under the larger harness, if would be routable away from the heat duct

How can you test if the air is flowing correctly?
Or test if everything is working fine?

The engine goes out next month for a rebuild. Broken head stuts but this can't be the cause I think

Problem solved.

It must be the heatsoak like Quiksilver mentioned.

I disconnected the hose and let the engine run. Air was flowing well through it,
when accelerating the amount of air flowing through increased as well.

After turning the engine off, you immediatly feel the hot air coming back from the exhausts.

I arranged the wires as well when I was there at the moment ;-)

I would think the airflow which isn't diverted to the HE goes to cooling the cylinders.
Many delete their heating system completely.
