Re: 1986 Proline 23 C.C. Rewire Project
The POSITIVE wire from the fuse4 block goes to the COM terminal on the switch --- NOT BAT 1 or BAT 2. Since the fuse bolck as you have is wired to BAT 1, even with the switch off, power is still fed to the fuse block. The switch is a traffic cop for current flow. If you had wired it to the COM terminal as directed, with the switch OFF there is no way power can get to the fuse block. Since you elected to wire it directly to BAT 1 on the switch, that alone means the fuse block is directly wired to the battery so why bother with the switch as it is doing nothing for you. Regarding the clicking, I would assume the noise you hear is the starter solenoid. I have no idea what "original ground" means. Every cable going to BAT 1 and BAT 2 POS and NEG terminals, as well as the POS cable going from the COM terminal to the starter solenoid needs to be the same battery cable size. Connections need to be clean and tight.
Here is how the switch is "intended" to work (although people tend to way overthink this thing and in the process screw up its real capability:
OFF:
All circuits wired to the COM terminal are dead. If you wire anything to BAT 1 or BAT 2 terminals, those device will not be affected in any way with the switch OFF. Only an automatic bilge pump for example would be wired directly to a battery.
BAT #1:
Starts the engine, charges BAT #1 only, and runs everything connected to the COM terminal. BAT #2 is out of the loop.
BAT #2:
Same function as BAT #1 but uses BAT #2 only. BAT #1 is out of the loop.
BOTH:
Self explanatory. Both batteries are on-line so both start the engine, both are chartged, and both power anything connected to the COM terminal.
For most boaters, except those with high power audio amps, the switch can be set to BOTH and left there whether anchored or not. If you are anchored for many hours then it would be best to switch to BAT #2. When ready to leave, chances are thet battery will still start the engine so you don't have to switch to anything else. BAT #2 needs the charge so leave the switch on BAT #2. If and only if the engine doesn't start would you switch to BOTH or BAT #1. When the engine starts, switch back to BAT #2 as it is the most deeply discharged.
