Mike, You are correct, the fuel pump, tach, and fuel guage wires are all attached to the wiring harness. The 8 pin plugs are famous for getting corrosion in the pins and causing all sorts of problems. I decided to check mine and one of them crumbled into pieces in my hand. I swapped them out for terminal strips. When I finished, I realized that butt splices would have been just fine on the engine side. Really no need to have a break there. If I were to pull the engine, I would disconnect each wire. No big deal. At the engine control panel, a terminal strip is necessary. If I want to work on the panel, it is much easier to disconnect the wires and remove the whole thing where it can be worked on. I run a 80 amp Balmar alternator, so doing a bypass on the amp gauge was a necessity. Don, #6293, Niceville, FL

I appreciate it. You are correct, the wire I am speaking of is separate from the plug, however, prior to reaching the plug, Catalina grouped 3 more wires to that bundle in electrical tape in order to keep things neat. I will test it today, I am positive it is the tach wire, I am just surprised they used orange rather than the stated grey in Catalina and Universals diagrams. I will complete the upgrade by using term strips rather than the plug, I just wanted to enhance my charging capabilities right away. I simply cut the 10 AWG orange wire on the side of the plug closest to the alt and connected it to the starter battery post. Eliminating the long distance the current had to travel. Also replaced the ammeter with a volt meter........ and put one inside the cabin as well. I spend weeks at a time in and around our local islands here in Ca. It is going to be nice not having to guess how much juice we have as well as how long we need to recharge.

The tach wire did not run through the 8 pin plug and could have been left alone. You could disconnect the tack wire from the alternator and do a continuity check with a owm meter, just to make sure. If I get down to the boat today, I will check the color of my wire.

I just did the recomended upgrade on my wiring harness. All the color codes match with the exception on the tachometer wire. The diagram from Catalina Yachts says it shoud be grey, however, mine is orange 14 awg.....also not to be confused with the orange 10 awg that used to go to the old meter in the cockpit panel and back, but now is connected directly to the starter motor for more efficiant charging. Anyone? Also would like to mention that the orange 14AWG wire starts to seperate from the wrap as it reached the alternator etc. Should this wire be grey is the question [Non-text portions of this message have been removed] [Non-text portions of this message have been removed] [Non-text portions of this message have been removed]
