Good morning.

Do you know how I should connect this cable to charge my riding mower? It's loose now and doesn't seem to charge.

I look forward to hearing from you.

Connect red wire to battery positive.

I had that idea at first too. And it seemed to work, but when the riding mower is off, the alternator still uses power, and then it draws power from the battery instead of charging it. So I wasn't sure if that would work, or if it wouldn't break.

Hello R.,

Welcome to the forum.

If I am not mistaken, this is a low output stator on a Briggs and Stratton that does not have a separate voltage regulator. It has an inline diode on the red wire hiding under the shrink tape (near the white connector). That diode is bad and allowing power to flow back to the stator when it should not.

It would help greatly to provide us with both the product identification label information (usually under the seat) and the engine model and type information that is stamped into the valve cover.

MTD made 100's of different model mowers, and it is a guess which one you have.

it's a MTD 12/91 with a B&S engine with the code 289707-0154-01

the terminal goes to the ignition switch.

The stator should not be drawing power unless the diode is shorted.

De aansluiting gaat naar het contactslot.

De stator mag geen stroom verbruiken, tenzij de diode is kortgesloten.

I have one function left on the ignition. Can I connect it to an L?

725-0267
B=Battery
G=Ground
L=Ignition
S=Start
M=Magneto

Disconnect the battery.
Then use an ohms meter check for continuity between B and L terminals with the switch in run position but not in the switch in off position. If this is correct then yes you connect to the L terminal.

Sorry don't have make/break table for this Indak switch per say ie i don't have MTD to Indak cross listed here.

Koppel de accu los.
Controleer vervolgens met een ohmmeter de doorverbinding tussen de B- en L-aansluitingen met de schakelaar in de bedrijfsstand, maar niet in de uit-stand. Als dit klopt, dan hebt u verbinding gemaakt met de L-aansluiting.

Helaas heb ik geen tabel met de juiste verhoudingen voor deze Indak-switch, dat wil zeggen dat ik hier geen kruisverwijzingen naar MTD heb.

Thank you for your message. We will try.

Found a make/break table.

Heres one for you to ponder , you cannot charge a battery whilst it sits on a concrete floor , Go figure

Hi Ozcub,

That is an "old wives' tale" that has been around since the early wooden encased battery days. That story has been disproven countless times.

The more important safety factor would be if a battery is "gassing" it is expelling a very explosive hydrogen gas. This happens quickly when people set a charger on too high of a setting.

Hey Auto Doc . did not say it was correct , I just said "ponder"

Hi Ozcub,

Yes, you said "ponder", yes, I pondered before I replied.

Not an attack on you, just stating what I know from many years working in the automotive and small engine industry.

People often tend to believe all kind of wild historical theories and stories that seem to be too good to be true because they are.
