My name is Thomas.
I just picked up a set of Lenco trim tabs and the directions say to connect the retractor wire (orange) to the engine tach signal. On my boat that’s the negative side of the ignition coil.
Is this what they mean? Or does it go somewhere else?
Thanks in advance.
If you want to use the retractor function of your Lenco tabs, you will need to connect the orange wire to the negative side of your coil.
I believe that the retractor function of the Lenco tabs will work by simple connecting the orange wire to your switched ignition wire, but this might explain why Lenco doesn’t seem to publish this anymore.
Thank you for all your help. I found that info.
By the by, following the suggestion on your web site, I got a boat wiring harness and a marine electrical panel from EzAcDc. It all works perfectly!
The EzAcDc boat wiring was easy to install and modify to my particular needs. I set it up independant of the ignition so the panel is live so long as at least one of the batteries is switched on.
However I am thinking that I want another automatic bilge pump, my third, unfused & wired direct – bypassing the main switch so it will pump any time and unattended while I’m ashore goofing off.
Any thoughts on that?
Thanks again for this awesome resorce!
You will want to have circuit protection for your third pump. All new bilge pumps have their fuse size stamped on them.
To wire this new pump correctly, install your fuse/breaker as close as possible to the battery. You will have two wires leaving your fuse. One goes directly to your auto float switch and the other to your manual bilge pump switch. The wires leaving your float switch and your manual switch are connected together (usually near the bilge pump) to provide two different ways to turn on the pump. Attach your bilge pump ground to your battery negative or a ground buss.
Sadly your trim tab link didn’t work. Pitty, as I like to know all I can about any given thing.
So conecting to the tach wont disrupt the tach reading? Is one way better than the other?
Sorry about that.
Do a Google search for “Lenco Bennet Lawsuit” and check out the articles on the Boating Industry site.
As for the trim tab installation, connecting the retractor wire to the coil will not disrupt the tach reading.
Have a great day,
