I'm getting ready to install a Trik-l-start on my 2015 Agile.
BUT..................
cannot tell which side of separator goes to which battery.
legend on separator says "main" and "aux"
but it looks like "main" goes to the coach batteries under hood.
(kind of difficult to trace)
Multi meter shows approx the same voltage on both sides.......
Ideas ?
IF it's like the
Trik-L-Start web site says, the BLUE wire goes to your Starter battery, the Yellow wire goes to your House battery.
The black wire goes to the frame/common negative.
After that, the House side will be providing the power that keeps the Starter side happy...
The PDF instruction manual, which uses the words "house" and "starting":

AHH... i now see that you're asking about the SEPARATOR .... hmmm... i would assume "main" is the Starter side.
But you can quickly test it: disconnect the Sprinter's "main negative disconnect" that's in the driver's pedal area.
That should drop the "starter" -side voltage to zero at the separator.
An alternate, perhaps easier test: clip on your voltmeter to the (let's say) Main side.
Now, without starting the Sprinter, turn on its key and turn on the headlights.
The "starter" side should drop a tenth of a volt or two.
(especially if you have a helper turn the key... the glow plugs will really pull it down for a few seconds)
Repeat that test with the voltmeter on the Aux side, which shouldn't budge.
