LMTV M1078 Tachometer

[ramdough]

No sorry I am going to use that one. It's a Medallion tach they make civ ones that are almost identical. The Internet is full of them.

Do you know the civilian part number for the medallion tach?

Has anyone done a non-OEM winch with mounting mid-frame?

I don't think there is a civilian part number for the military tach. It has has a part number (which is here in the parts spreadsheet in my signature), but you can't just buy it on the open market. What Suprman is saying is that there are civilian tachs that are the same size, that are not wired the same but can be wired in a different way to make them work.

Darn, you have such a glorious invintory of parts I thought you might be holding on to a few. I'm sending you a parts wish list now, emailed!

Please can send it to me? I need install tachometer in m1078 a0 allison wtec2
Any suggestions?
Thanks

I have the switchbox tach housings with harness and generic mil surplus tachs that fit. They dont plug directly into the harness you would need to wire the tach to the harness.

Tengo las carcasas de tacómetro de caja de interruptores con arnés y tacómetros genéricos de excedente de mil que encajan. No se conectan directamente al arnés, necesitaría conectar el tacómetro al arnés.

Does your alternator have the blinking lights on it?

I will check this lights oi don't know what lights you're talking. My engine is 3116 m1078 a0 of 1998

Are you talking about the panel lights in the cab? When i push the button :test lights?

Tilt your cab and start the engine. See if you have two, alternate blinking green lights. If so, an aftermarket tach like this will work. I'm speaking from experience of mine and a friend's 1078.

Wonder if they make one small enough to fit in the useless air filter gauge hole.

Incline la cabina y encienda el motor. Vea si tiene dos luces verdes intermitentes alternas. Si es así, un tacómetro del mercado de accesorios como este funcionará. Hablo de mi experiencia y la de un amigo 1078.

Las luces que dices están en el motor o en el alternador, no las veo de todos modos.

The blinking lights are on the engine or on the alternator. Anyway i didn't find them. This is the alternator i have.

The indicator lights are on the voltage regulator on the alternator. Yours may have a different regulator which, in my experience, won't drive an aftermarket tach.

So you think I can only assemble the standard one that comes with the hmvee connections? So I I must have somewhere the connector for the tachometer not? And if not, where I connect it, Will I have to install a tachometer sensor? What do you recommend?

I can't help you there with the hmmwv tach. Maybe someone with more knowledge on them will chime in. I know my friend is running his hmmwv tach off of the alternator that I described. You may be able to drive it off of the speed sensor on the bellhousing. That is where the factory tach is driven from.

METROThank you very much I will inform when I solve it, is that here in Spain there is little information and pieces of lmtv, I have looked on the Internet but I do not find the tachometer of the m1078, I only find the one from hmmwv. Where can I find it to ask for send it to me?

No puedo ayudarte con el tacómetro hmmwv. Tal vez alguien con más conocimiento sobre ellos intervenga. Sé que mi amigo está usando su tacómetro hmmwv con el alternador que describí. Es posible que pueda sacarlo del sensor de velocidad en el campanario. De ahí es de donde se maneja el tacómetro de fábrica.

My regulator is a n3030. I note that some of the other posts with regard to tapping the regulator for a signal, used a different regulator. It only has two posts and one military style connector on the front. Do I still use the the white post?

I have the same regulator and a 76761-n1506-1 I also want to ride the tach, did you get to ride it properly? Where did you connect it at the end? A detailed solution would be great
Thanks
