I am confused as to what the purpose of the "I" post does on the starter relay. What application is this used for?
That's under maximum load - like an overheated, frozen, or hydrolocked engine. The max normal current is 200A.No, Ford specifies that the maximum load is 800amps according to your link.
All Ford documentation refers to it as the starter RELAY. Helm, Chilton's, & Haynes refer to it as the starter relay. Only parts suppliers categorize it as a solenoid, so the parts monkeys call it that.As for the relay vs mag switch debate.
I don't need to - I can buy one anywhere, and all of them last thousands of starts.Build a relay that can handle the amperage of the starter. Install it, and it will fail within probably 50 starts.
You're the only person I've ever encountered who calls a starter relay a mag switch. I can't even find "mag switch" on WikiPedia, Amazon, Grainger, or McMaster/Carr (though they do have magnetically-operated switches). So IDK where you came up with that term.They are called mag switches, because that is what they are.
Anyone can find a relay rated for 30-250 amps, with any kind of construction, including solid state, Mercury, toggle, or disk. I have a few of each in my junkpile.Relays do not have rotating discs in them and do not employ arc burning, etc. Relays just open and close a contact, and thus have to be low amperage.
A typical "relay" is a solenoid-operated switch. A typical solenoid is an electromagnetic linear actuator. So MOST relays contain a solenoid, and most relays are electromagnetic devices. I have no idea what a "mag switch" is, but if you want to call relays that, no one can stop you.So in reality, the Ford fender wall mag switch has more in common with a solenoid, than a relay.
Is that what an eB uses?...a HD starter...
Why not just post a link to the specs for the starter that a typical eB would use???...about 30% than the older Direct Drive starters. Here is the link:
No, they're natt. You're using formulas for resistive DC loads, and as we all know, a motor is an inductive load whose commutator effectively turns DC into AC, so the formulas are totally different, and MUCH more complex.Watts are watts...
No, that number came from your imagination. The manufacturer's numbers are 140-200A under normal conditions.Comes to 436.3 amps under normal conditions. That is from the OE Manufacturers website.
...and your point is...? Do you think Visteon is over in a corner building starters, and Ford is trying to come up with vehicles that can use them? Or do you think Ford designs the vehicle, and the starter needed by the vehicle, and then has Visteon (a company that was originally part of Ford) build them?Ford does not make starters, neither does Motorcraft. I believe Visteon is their current supplier of choice.
You're so far off-topic that I don't even know what you're trying to show.you can easily see why the Denso is a major HD upgrade over the DD or PMGR starter.
