Hi all, new member here. I have an Ariens EZR 1540 model 915008. My Briggs OHV 14hp broke connecting rod. I replaced the motor with a Briggs 16hp opposed twin model 42A707 type 2238 E1 code 0006055A from an MTD that had a non electric blade engagement. My ariens has an electric PTO. When the motor is running at 2700 rpm i have voltage reading across my battery at 13.73vdc. When I switch the blades on voltage drops to 12.2vdc making it so my mower dont have enough juice to start next time. coming off the motor I have the kill wire, charge wire and headlightwire. charge wire is hooked to battery + on starter solenoid, kill wire runs to ignition tumbler, headlight wire is taped off since I have no lights on the machine. Anybody have any insight fr me? I assume i have to change alternator and flywheel. would I be better off
money wise replacing the briggs alternator or switching to an automotive alternator and welding up mounting brackets? Thanks in advance

The photo we needed to see is the alternator plug.
Briggs use a code system with the type & shape of the plug as just about all of them are interchangeable.
So you should be able to take the alternator off your old engine & fit it to the new one.
The caveat on this is the flywheel with the magnets in it.
There are two sizes of magnets.

Dang, I dont have the old motor anymore. I will upload pics of the alternator plug and flywheel magnets shortly. Thanks for the willingness to help me!
