I have installed a an Orion TR 12/12 30A non isolated to charge my lithium house battery. for charging whilst driving my motorhome. When I start the engine my rev count and speedo bounce for about 20-30 seconds. Should I be concerned? how do I stop this? is it a software issue?
Live from battery via 40amp fuse too Orion DC/DC input. Earthed, output directly to lithium house battery via 40amp fuse. The standard green plug (Loop) installed between L and H.
Thanks for any help in advance
