The engine was overheating so i did some troubleshooting on the way. The following results arose:
-With the airconditioning on, the high speed fan kicks in for a short bursts
-Did multimeter voltage measurements on the low speed fan relay connectors:
Connectors 85&86 : Steady 13.73 V
Connectors 30&87 : Slowly Rising up to 10 V.
I think the resistor is 0.22 Ohms multiplied by 30 Amps that would give maximum a 6.6 Voltage drop from the battery's voltage (which mine measured is 14V with the engine on).
If i understand the cicruit schematic correctly, 30 & 87 are fed into the fan
So, the 30 & 87 connector's voltage seems quite reasonable . If there was a fault, i would probably not register a voltage reading at all. What worries me is :
Swapped the relays between low beam and low speed fan. The relay of the low speed fan is powering the lights a-ok......Is this relay supposed to be identical to the low beam relay ? (mine is)
So it must be either temperature sensor or the fan low speed motor.
QUESTIONS:
-Are the 13.73 V in 85&86 connectors reasonable at all?
-If it is the temperature sensor where is it located? (from forum reading i know there are two of them -which do i change?)
-Are there other sensors/parts included in the system ?
-If it is the temperature sensor, why does it not show on the temp gauge? The temp gauge rises quite smoothly....
-What are the chances of a possible wiring problem between ICE and fuse box?
