1986 XJ12 Series 3 Blower Motor Testing (Off Vehicle)?

Postby wgsouter » Tue Nov 07, 2017 9:07 pm

Hi and a follow-on from my previous topic where I replaced all of the elec components on the Blower Motor Circuit Board (thanks for your advice there).

Anyway, having renewed/replaced all of the components on the circuit board (transistor, diodes, resistor and capacitor) and then replaced the relay inside the air mixer box, I have now reassembled the blower motor ready to refit into the vehicle. However, as this is an on-going long-term rebuild project, I have no idea whether the blower motor will actually work until I complete putting the car back together ... is there any way to test-run the blower motor on the bench at its various settings by 'just' applying power to particular pins? I did run the motor by connecting it directly to a battery, but this does not confirm whether my 'replaced' elec components are connected/working correctly.

Is there a way of testing the motor plus control circuit on the bench?

Kind Regards
