Blower Motor Current Draw, HEATER

Blower Motor Current Draw Test

1 Separate the blower motor ground (black) wire from blower motor resistor.
2. Connect positive (+) ammeter lead to female spade connector on motor wire, and negative (-) ammeter lead to blower motor resistor.
3. With a fully charged battery, operate blower in each switch position and record current draw (amps). The current draw for each switch position should approximate the values shown in the charts in Figs. 9 and 11.
