Brand new Intek 13.5 ! How to hook up ?

I've just mounted a new Intek 13.5 hp motor on an old MTD riding mower ... it has a 6 pin connector, unlike anything on the old MTD harness .

I would like to jump start directly to the starter motor terminal, and run the mower without a battery.

However, I realize the carb solenoid probably needs constant voltage (dc ?) ...
and this motor probably has an auto compression release that needs to be energized. So I'll run with a small mower battery If I have to.


Can someone tell me exactly what each wire is for on the Intek , or point me to an accurate circuit diagram ? The one included with the motor, and those I've found so far online are basic and generic.

This mower has no electric clutches or anything, and I'm not interested in connecting the headlights at this time.

Briggs Stratton model 21b807 0116 b1 0811252a

Any help would be appreciated because the weeds are taking over !

Hello SUPERSKIP,

You can run this engine the way you want with no battery, There's no power needed for the compression release. Just remove the carb solenoid and cut the center plunger tip off flush with the threads with wire cutters then re-install.

To wire this engine to the tractor I would need to know how many wires are in this 6 pin connector and what colors they are.....


Oh, The black wire in this connector should be the engine kill wire, It can be hooked to a toggle switch to shut the engine off.

Two wires run from under the flywheel to the plug. The red one with the black lump in it near the connector is the alternator charging wire and it would be connected to the battery positive, should you decide to use a battery. The other one is AC current that runs the lights.

The wires going to the solenoid are positive and ground, either connected to either will work if you want to use the solenoid, or clip it off as 31Ytech suggested.

The black wire coming from the coil goes to a kill switch. Ground it to kill the engine. Never connect it to power, even momentarily, or you will fry the coil.

I suggest connecting a heavy wire to the starter, and jumping to that instead of jumping straight to the starter, or you will arc up the starter post eventually, possibly melt the housing where it connects, and you'll be needing to fix the starter eventually. Better to just replace a little bit of heavy wire, or skin it back a little further to get a good connection.

Thanks for the info, guys, willl be put to use this weekend. Here's a couple photos if you care to comment further on the electrical hook up ...

SUPERSKIP,


This being a "old" MTD, Your ignition switch may not have provisions to operate the fuel shut-off solenoid, If you have a five post switch it doesn't. If this is the case you can cut the tip off the solenoid as I mentioned above, That will leave you with only two wires to hook up from the 6 pin four wire connector as below;





EDIT; Slide that fuel line up on the fuel filter further and put a small clamp on it, Wouldn't want to hit a stick or something and snatch it off.....

Good Luck
