Question 15 Rjc-4r8/1562c

I have a question about a cranking limiter in this unit. This is a 12volt dc system but this cranking limiter is 6 volt dc in series with a 3 ohm 10 watt resistor. I would like to know why this relay was set up like this?
My second question is why don,t I see more RJC units out there.

Bill I have had the same thoughts about the limit switch.Never have found an answer,guess some brain thought that was the way to go.Alot of onan units where only built when they had a request for one.The RJC is not a common unit like the JC.The motor home units where produced by the truck load because of the demand for them.Same for the JC line.The RJC is not rare just not alot of them out there.

If i remember corectly with the 6 v coil and the resister you can adjust the time by changing the resister or having a adjustable resister. Sometimes manufactures choose one part # to stock and change the parameters with a resister?
