Chinook RV

Gentleman, I have recently developed an intermittent starting issue. It was easy to trace to the " smart solenoid" behind the battery.
I have cleaned all the connections and ground. But still having the same issues. I looked through my owners manual but there is no part number. Would anyone have any information on where to purchase this part?

Thank you

It is the SurePower, and here is a link to the document in the Reference subforum.

It should not be related to starting issue unless your coach batteries are weaker, and draining your coach when it connects them due to bad solenoid/relay. The way it *should* work is when the coach batteries is already fully charged, it will connect and start charging your coach (or starting) battery.

You can disconnect the connection to the coach batteries in the battery terminal under the water heater. It is not a long-life item, so maybe it is defective, but I won't know until you check it with a voltmeter and check the behavior with the specification.

Some of us had replaced the old SurePower with other device (BlueSeas, for example), and may have spare one that can sell/ship to you. There are many thread on the SurePower on the forum if you do a simple search.

Thank You. Now I have a path to follow.
