Possible split charge relay problem

[Hillclimber]

Just come across an interesting electrical issue on my 10 series Alphie. It's fitted with a solar panel on the roof and there is a Portable Power Technology split charge relay between the main and leisure batteries. The solar panel is off according to the 3-way switch on the auxiliary panel at the rear.

This morning I heard a regular clicking noise coming from the front of the Alphie and found it was from the relay. Presumably it is sensing a full charge in one battery and switching to the other. Sensing that is also fully charged, it switches back, ad infinitum.

Not heard it before, so wondering if I have a fault, and also will this switching slowly discharge one or both of the batteries until the next time it is driven.

Have you tried disconnecting the leisure battery, and/or the solar feed ?

As the leisure battery is fitted under the passenger seat, access is not a quick 5 minute job! What I have done is to remove the lead from the +ve post on the starter battery that went to the relay. That has stopped the relay flip-flopping while I further research what the problem may be. Thankfully I have no plans for using the Alphie for the remainder of this month, so will have time to get this sorted.
