Who can tell me how I might check the operation of a coolant temperature sender on a engine management system.
Someone mentioned running the engine and measuring the resistance on the sender?

Spyder-WISD 07-09-05 11.6s @ 125 MPH

Speedster-WISD Nats 05 14.4s @ 89 MPH

Jet cruiser-Coogee 22-09-05 900 deg C @ 110,000 rpm

First you need to find the specs for that particular engine, and yes you are measuring resistance, some senders increase resistance with temp, and some decrease resistance with temp, so you need the specs.
