120 BS Starter

[guido]

Hello,


This is a photo of the starter. It is on a Snow thrower with
a B&s engine. The label is pretty clear on it's use and
capacity,

Guido.

My apology to the correctness policy. It is not A brain to fingers coordination day.

120 volts starter system on a Briggs and Stratton engine, >p>Guido.

What is your question?
Plug in your extension cord and press the red button.

Have the same rig on one of the last tecumseh OHV snowblower engines. Works just dandy. Just plug her in. Never ever had one apart.

Hello sde,

Just show and tell. Some one may benefit from the post.
P.S. It is my personal Snow thrower since 2010,
Guido.

So, are there diodes or a rectifier in that black box to make DC or is the starter motor AC? We have had one similar for 20 years, it works great.

My Craftsman with a Tecumseh engine has a 120 volt AC starter motor. It has not given my any problems in the 15 years that I have owned it.

Hello Mule Meat,

I plugg in mine once, and it started right up!. Will
probably last for ever HE HE. It starts with the pull rope
and on the first pull every time,

Guido.

Hello Russ,

It is a 12volt starter. 120 volts input 12 volts output. Rectification in the box, nuch tike a battery charger. Capacity determines rectifier type and size,

Guido.

So, there is a transformer in the box too?

Hello Russ,

I have not seen a system that does not have one. The A/C is rectified at transformer secondary output, just like a battery charger, As I said, it depends on the capacity. Low power rectification Like a phone power output is usually a 1/2 wave rectifier, while higher outputs are rectifier bridge. Welder at times also use feed through diodes rather then rectifier bridge for DC output,

Guido.

Guido, I'm pretty sure if you open that box you won't find a transformer.

Starter runs on rectified "line voltage".

Here's a drawing of the older version:

I'm pretty sure that if he was to read that tag. He would find that it has a 120 volt 60 Hz starter. And more than likely even find a part number for it.
