The heater is a winner

I tested the heater today (after replacing the fuses in my multimeter. Why do they specify 630ma?)

Here are the stats. All reading are in Deg C

Voltage after test: 656V

Ambient temp: 28C

Fan on Low: 45C 

Fan on 2: 35C

Fan on 3: 39C

Fan on High: 32C

Minimum variance from ambient = 4C - fan on high

Maximum variance from ambient = 17C - Fan on low.

I am happy with that. After I get it the ute road legal, I will look at reverse cycle air conditioning.

The speed sensor problem is unresolved. I will probably bevel the teeth on the drive flange.
