Older Bolens tube frame's used Battery Ignition Switches. Todays electronic control engines use Magneto Ignition Switches. From my understanding "B" battery ign sw shuts off power to the coil which stops spark whereas "M" ign sw grounds out the coil packs at the switch to shut down. I have read these switches are not interchangable - ( "B" shuts off / "M" grounds out) . Is my understanding correct or somehow these 2 types of Indak switches are interchangable??

Welcome to the forum. you are right by believing that the two are NOT interchangable. I thought the majority had I for ignition on the ones that suppied battery voltage and M for the ones that ground the prmary.

Ran into this when i replaced my H16 engine with a 16hp twin cylinder Vanguard. (btw - what a improvement! fit perfect - not a chop job) I knew of this & installed a magneto type ignition switch. Last year I was asked to wire up a older Bolens with a ignition coil, He gave me a box of wire & parts and a new magneto type Indak ignition switch. I told him wont work. He's been to mower shops & they say it will but wont / cant do it. I aint the brightest bulb in the box but been doing this stuff over 35 years.

How can i talk private to Bolens 1000?

Thanks all so very much.
