    Blew another seloniod on 1976 Ford 302

    Thanks Mike, I was going to route that blue wire (it is actually purple) straight to the selonoid (I) terminal, as it connects to the key (I). Attached is the new schematic of how I plan to wire it, hopefully this weekend. Not sure if there is a a dummy light, and I don't think I have an ACC...

    The starter I have says: NOSE EXTENDS 2 3/8" INTO FLYWHEEL. It also says it is compatable with the starter I found at West Marine. Any way to find out which flywheel I have? Hi Mike, Thanks for responding. I am going to re-wire all the wires from the key switch to the selonoid and to the...

    Does anyone have a data base that would tell me the number of teeth for my ring gear for my model number of my OMC outdrive? (engine serial # is: W524031. The OMC model is #990231M - 1976 Ford 302 CID Marine 190 HP) The engine was running before I had it overhauled, but wouldn't rev over 1000...

    I'll do the wiring and the tests and see what happens. The starter is really hard to get to.

    I'll re-wire and do the tests this weekend. I found a Sierra Marine starter at West Marine that says it is compatable with most OMC Ford 302s and 351s for $257.99 and is rebuilt. Not sure I want to go there. I'll do the tests.

    I'm not sure that you got my concept on the purple wire. You have to look at my last schematic, The purple wire from the voltage regulator heads towards the key switch (I) via the purple wires feeding the gauges at the volt meter. The key (I) terminal has another purple wire that heads to the...

    I haven't done the voltage drop tests, yet. That's probably next, maybe put in the new wires to the key from the seloniod. That way everything is new, New key switch, starter, selonoid, wires and battery - that is about all there is to the starting circuit. That is why I suspected maybe I have...

    I saw my grandkid, too. I put in the new 0-gauge cables, took out the spark plugs and spun the engine with the starter, and same slow crank! I did it for 20 seconds for 7 or 8 times and it didn't speed up, just got slightly slower as the battery ran down. It did still crank at 12.3 before it...

    Yes, I did get three battery cables. Thanks Mark! I will get to this over the weekend.

    Blew another seloniod on 1976 Ford 302

    My 302 has GT 40 heads, which bumps it up to 190 hp from the 175 of the standard heads. I believe that that means that it has roller lifters, but not absolutely sure of that or exactly what they replaced. So if I spin the engine with the starter with the plugs out at a good rate, will that prime...

    The wiring harnesses are not available at marineengine.com. They don't have the battery wires, either. I will have to find some somewhere. I don't think they put in a new cam. My thought on the compression test was, if the plugs are out, the starter motor would turn it over at a good rate, and...

    Yes, of course, you are right, it was a voltage drop test. I am ordering some new battery cables, since the drop of .3 and .7 were not adequate. I will do the four voltage drop tests for slow crank again after new battery cables. Also will pull the spark plugs to ensure motor is okay. I may go...

    Blew another seloniod on 1976 Ford 302

    I haven't primed the oil system, I am kind of a YouTube mechanic, but I did find out how to do that, taking apart the distributer and hooking up a drill to spin it at high RPM. The timing is close, and not the common mistake of being 180 degrees off. I can do the voltage drop tests. Some wiring...

    Dang! Still slow crank and only 15 seconds of crank time. Mark, I thought you really had it wired! All of your recomendations aligned with what I suspected. Asside from re-routing the black and orange 8 gauge wires, I also re-routed the other accessories the were hooked up to the batt terminal...

    I am waiting for the new selonoid from Amazon, but made the changes to the wiring with the black and orange 8 gauge wires and also updated the schematic:

    Wow, that's great! I thought that black 8 gauge wire was the culprit. I was also puzzled why the alt output went to the key, and right back to the selonoid. I will do those changes for sure and go from there! I have done load tests on the battery and they check out in the green. Also various...

    Thanks for your reply. I do have a remote switch to jump the + and the (S). As far as wrong voltage or bad connection, do you see anything on my schematic around the selonoid that looks suspicious? Any wrong connection?

    The wiring is old, and when I cut the wires back to put on a new connection, they seem somewhat dark and corroded. I am wondering if I should just re-wire the whole thing, maybe get new gauges (although they seem to work fine)? All the high amp wiring through the selonoid is new, clean and huge...

    I did some exploratory and found that the black 8 gauge wire attached to the starter side of the selonoid is the negative ground to the gauges, and the red 8 gauge wire on the battery side powers up the key switch (B) and the gauges. Still not sure where the wire from the (S) terminal goes...
