Do you publish contact resistance for your Freedom Contactors and Starters?

We do not publish documentation on contact resistance for our contactors and starters as there are many variables that affect the resistance measurements. These variables include:

1. The meter used (a standard fluke meter is not adequate)

2. Where the measurement on the contacts takes place

3. The oxidation buildup on the contacts

4. Dirt buildup on the contact surface

We can offer that a measured contact resistance below 5 milliohms indicates acceptable values given the variables above. Because resistance values are low, it is very easy to have a difference of more than 50% between poles.
