I bought a Smarcom split charge relay from ebay but it does not seam to charge my leisure battery. I wired the split charge relay according to instructions, but when the motor is running there is no +12V feed to "Ext. Bat". There is a continuous "click" sound from the split charge relay.
The seller didn't reply to my messages.
Please explain to me how does the slit charge relay work and how I can solve the problem.
