My starter is at a shop getting the lug replaced with a threaded lug. I'm going to use a push button start and solenoid. Question is where do you mount the solenoid and the push button? Unlike the B's and C's there is no metal tool box in that area. If someone has a pic or a diagram that would be nice. Thanks ------------- Everything is impossible until someone does it!

| You could just use the start position on the key. |

On my WC that I did the same conversion to, I “hid” the solenoid inside the headlight mounting pan under the gas tank. Years ago I converted an Autolite starter for my C and the shop mounted a small cylindrical shaped solenoid right on the starter using the tapped holes that held the original mechanical switch. ------------- HANSEN'S OLD ORANGE IRON.

Here's what I did. Starter solenoid mounted to stater. I had a spare D-17 key switch I used, kinda the same vintage. Very simple and clean. Turn the key to run mode, turn to start and key returns to run mode when released. But any parts store will have a simple start key switch.

I like how you have mounted the solenoid. I will pick up my starter this week. ------------- Everything is impossible until someone does it! WD45-trip loader 1947 c w/woods belly mower, 1939 B, #3 sickle mower 1944 B, 2 1948 G's. Misc other equipment that my wife calls JUNK! |

I got my starter back from the shop. I mounted the solenoid on the battery box and the push button I mounted using one of the bolts from the quadrant. Nice and convenient. Got it all wired and no starter. End was my battery was no good. It may have started with the old switch and a new battery but I'm happy I went this way. My key is on-off so I wired the push button through that so the key has to be on to turn it over. Tractor never started so good. Thank's for the help and suggestions. ------------- Everything is impossible until someone does it! WD45-trip loader 1947 c w/woods belly mower, 1939 B, #3 sickle mower 1944 B, 2 1948 G's.
