Thread: Followed Me Home, '33 Build

Tweet

Today I changed the old coolant and it was easy peezy! I first drained the system and measured the volume to find that 2 gallons would be more than enough. At the Auto Parts Store a gallon of concentrate was $15.99, or a gallon of 50/50 dilluted was $12.99...... So I can buy 2 gallons of 50/50 for $26, or one gallon of concentrate for $15.99 and add my own water to have 2 gallons? Are people really that stupid? Yes, I came home with one jug, and quickly had 2 gallons of 50/50. Since I had drilled a 1/8" hole in the thermostat plate the fill was super easy with the new fill neck!

Next is replacing the relay based pushbutton start with a traditional keyed ignition switch, another of those things that I've tired of since the initial build...

1. - YES, people can be that stupid!
2. - What's with the PB start? I thought everyone loved it? I don't have one so enquiring minds want to know! Do tell.
what's the hub..... bub...??? LOL

Back in 2010 the options for PB start were limited but I found one from Watson's StreetWorks, a multiple relay system with a maintained "Accessory" PB and a second spring return to "ON" PB for "Start". The down side is that there's no security, like the key fob on a modern PB start, so the only thing you can do is hide a toggle switch that breaks the connection to ground. I have two, one a simple toggle, and one that's a security key like you see on vending machine coin boxes, the circular key with custom cutouts. A problem is that the "Start" PB engages the starter, then spring returns to "ON". If the engine does not start on the initial crank you must press the PB to "OFF", then the next push engages the starter again. With my EFI, the logic enriches the injector pulse width on the initial "Start", then if you reengage the starter it drops back to the normal "RUN" pulse on the injectors. However, if you turn the key "OFF", it resets the logic and triggers the enriched pulse. For me, with the PB Relays, every time the starter is engaged it's pushing extra fuel, tending to flood the engine, or worse wash the cylinders. It's time to abandon the relays and PB's, and put in a key switch.

AH! I get it now. I think it's strange "they" didn't provide a circuit to power the ignition during crank but... no matter.
Applying the KISS principal is usually best anyway. As an aside, The Ford starter solenoid from the early 60's with 4 posts, the post closest to the battery terminal connection as you probably know operates the relay.. the one to the right of that is to feed battery power to the ignition during cranking. Or you can also add a wire to the starter connection at the solenoid to power the ignition during cranking.. (if you need to)

My ignition is powered during crank now. The issue is the EFI logic that applies a longer injector pulse (more fuel) during the first crank, and that my pushbutton makes every crank a "first crank". I have to turn the ignition "OFF" before it will energize "START" again. Watson should have used one button for ACC, one for IGN ON, then one for START which means that I could also add a momentary button for START and take that wire off of the relay that feeds it now..... but then I'd have another ignition switch in my "stash".

I wasn't "speaking" directly to you.. more for um... general consumption amongst the masses - being what they are. And the "stash" is what we used to bring to the swap meet. I miss those days

Yeah, whether you were talking to me or not, the masses in general, or a specific member in need is moot. As I thought about it I decided that I really don't mind the PB start, but I HATE the ON-OFF-ON-OFF of the ignition circuit during START so I ordered an old school chrome momentary "START" button from NAPA and I'm going to do that for now instead of the key switch. I think I'll like the change, and if not I'll use the hole I drill for the new PB for my key switch!!

I think that will solve your problem as it will function the same as a normal ignition switch when turned to the 'start' position.

When I was doing my coupe I was intrigued with this same setup. I had seen it at the Nationals in Vermont with Dave White ( IC2) that'sgoing back some huh?? LOL. I liked the tech part and I wanted to hide the button to keep the dash clean. But I was unsure and decided to wait. And then the state changed how they wanted to title these cars so the rush was on and simple key switch was the priority. But I was always curious!

I don't remember when Ford eliminated the "push button to start" feature. I seem to remember it was on the 52 I had and for sure on the 36 and 40. The ignition key on the 40 also locked the steering column.
