I know we have discussed these things at some length but I'm not about to go searching for what I need so let's talk about it.
I have had for some time a lot of difficulty starting my engine off the emergency bank. I have now systematically replaced everything except this Perko OFF-1-ALL-2 switch. Still the engine won't start and the solenoid just goes click-click-click.
So I figure the switch must be dodgy. This morning I pulled it out and discovered that stripping it for inspection is pretty much a one-way street. So I checked the resistance across the poles, I connected it to a battery and checked voltage drop and saw nothing significant but then I re-installed it and started doing what I probably should have done in the beginning. Please read the following.
I have a Xantrex Link 20 that allows me to check two different banks.
When I had everything connected, I started the engine with the battery switch set to position 1. The Xantrex reported about 25 amps of charge going into battery bank 1 and nix into battery bank 2. This I would have expected.
Then I switched the switch to ALL and the Xantrex reported the same 26 amps into bank 1 and 36 amps into bank 2. This seemed about right.
Then I switched to Position 2 and the Xantrex reported nothing on bank 1 (expected) and nothing on bank 2.
This must mean that the switch is stopping current flowing to bank 2 unless the bridge between bank1 and bank 2 is made (ALL position), ergo the switched is knackered. So why am I getting readings going the other way?
I have so many things to spend money on I don't really want to waste it on an unnecessary switch but it looks like it will be a necessary switch.
