Do I agree? Meh!

Thanks for refreshing how to reverse a DC motor. Just like the 2 wire diagram and like the DC motors I worked on except they used vacuum tube amps instead of relays. :wink: Wonder if blue and green wires have have any significance? :lol:

ha...maybe a loose connection to the tube color codes. I think blue was a signal wire but green would've still been ground. :noidea:

the ate up harness that came with my used CMC had blue and green for up and down respectively. Opposite what is shown in your diagram above.

Maybe I misunderstood your terminology; i consider this a 2-wire circuit as well (this is how I wired mine but with 2 trim switches):

The other diagram (top) is only 2 wires to the motor and polarity and ground are reversed to change direction. In the brush holder pic, I only saw 2 wires, that's why I asked. Sent both diagrams in case the 3rd wire was hidden. The bottom diagram has 3 wires into the motor, Ground and up/down or CW/CCW.

Just swap blue and green wires or turn the switch upside down, either way. LOL

Blue sky for UP and green grass for DOWN is kind of a standard for TnT in most cases.

Darn, wish I go out for a drink but everything is closed for at least 2 more weeks. :blue:

Ah, so your top circuit defies color code standardization.

there is no ground to the motor in the bottom diagram... maybe you're looking at the switch leads?

I left my house yesterday for the 1st time since last Monday just to drive the truck around and exercise the 4x4!

 

[GA_Boater]

You're right. I was looking at the switch. Now I really need a drink to get my head straight. The bars are still closed. :frusty:

What was the issue with your CMC PT130 that it needed work? :happy: :laugh: :joyous:

I'm glad I trusted my intuition with the warm cable running out to the TNT motor.

The black/white is 12awg non-tinned (vs my yellow/red 10awg tinned).

That's only a 3/8 NPT thread strain relief and I bought the largest cable diameter possible (0.38"-0.44" cord OD).

For what those units cost new, you'd think the contacts would be 24 k gold.

 

[GA_Boater]

Boy, ain't that the truth! Every time I think about getting one, my brain goes into convulsions. It has something to do with a new or used CMC TnT unit costing more than I paid for the boat.

IIRC, I got this one for a bout 1/3 the price new. Pee Wee Herman to Arnold Schwarzenegger with a few upgrades.

Get to the Chopppaah!

I got a used PT130 from a forum member here for 150

I have no friends. And no loose change either.

No Friends? Are we chopped liver? :noidea: :lol:

I've been keeping pretty busy on the rig but time is starting to become divided now that spring has sprung.

Last of the CMC wiring update...I upgraded the main connector to a molex waterproof rated to 46A.

^^^ connectors on the right pull-in to lock...and the ones on the left push-in to lock.

for push to lock, you feed the wires through 1st, then crimp on the connectors...kind of a pain to maneuver that big crimpers in there.

while push-to-lock are straightforward:

I'm using a Humminbird 898c side imaging fishfinder...I like to keep the GPS puck as close to the transducer as possible to that structural waypoints are on the $$$. It also needs to be high enough to clear the outboard.

the CMC setback gives me a ton of clearance for the SI transducer:

 

[classiccat]

Moving on to the interior, the side bracing gives me an alternative to fastening the splashwell pillars.

I bent up these 0.090" "J" brackets rather than going into the deck.

A little trick...don't throw away those large-flange rivet heads if you've had to drill any out...

...they make perfect sized washers for the replacement rivets:

"bucktail" side:

3/16" backers for the cleats:

My midship cleat right where the hull sides start to taper in:

With the sidepanels installed, i'm finally able to mount the power pilot...epoxy plug placement was perfect.

Hammer down position where I'm able to tilt/trim with my right index finger:

I also lubed the old 400 series control cables and nipped a portion of the annealed end to give me a little more adjustment room at the engine (the adjuster/retainers were both at the end of their travel). Now they move with zero effort/resistance.

For lubrication, I clamped some 1/4" fuel line, sprayed with chain/cable lube and connected it to 40psi of compressed air...resulting in black sludge spewing all over my white splashwell! :lol: Rinse & repeat until it comes out clear.

that's about where we are! Thanks for stoppin' by! :yo:

Well............................................................ :bounce:

Hey, a mini-radome.

If that the last of the electrical work? Pretty soon all you'll need is an all clear from the governor.

 

[Watermann]

Oh yeah those smalls are falling by the wayside pretty quick.

So does the CMC unit work better now or at least work after all that? :lol:

Almost done electrical; I have to connect the tac, accessories and install the kill switch.

My #1 obstacle is now the DMV.

Like a dummy I let both of my registrations lapse (i wasn't getting notifications b/c my email changed when I relocated) so I have to re-register in person.

DMV offices will be closed for at least another month.

Indeed! biggest hurdles are having the stones to drill into something that you spent countless hours prepping/painting to perfection :lol:

The CMC moves with some authority now even with that little tractor battery...and all of the wiring stays nice & cool.

I'm not exaggerating when I say that it was a fire hazard...I have a feeling someone downsized that main cable to 12awg...b/c it was getting HOT with just 2 up/down cycles.

Speaking of batteries, I also picked-up my Interstate starting & house batteries at the local distributor this afternoon.

I wore a facemask, gloves and the entire transaction was done in the parking lot! ainkiller:

Not able to schedule an appointment? I was able to do that for my drivers license, but that was a couple weeks ago.

Boat is coming along nicely!!

I have been keeping up with all your post.. You do amazing work.:rockon:
You must have a lot of electrical back ground experience along with many others..

Watermann ^^^ man in the bubble.. That's great..
