[Healeys] current draw of wipers

[john harper]

Bob

Not all big Healrys fit the DR2 Wiper motor. The BN1 fits CRT.

If the full load on the dynamo/generator is a little above its full
capability then there will be a small drain on the battery. There will be a
greater load on the battery when the engine is idling when the generator
current drops. So over time if the full load you mention happens all the
time then slowly the battery will lose its charge but only if the full load
you suggest is there all the time, which is unlikely unless one only drives
at night with wipers on and never in the daytime with the lights off.

The stall current you mention is what happens if for example the wiper
blades are frozen to the windscreen. If this were to happen the high
current of about 8 to 10 amps will soon overheat and damage the motor so
inside the motor is an overcurrent thermal devfice that disconnects the
power, so there is no need to be concerned about this.

Best regards
