75' 460 starting problems
So I took my F-350 to haul a load of hay Sunday. I got it loaded, shut the barn and drove away fine. I pulled out onto the road and saw my in his duramax
, we stop to talk an the middle of the road to talk like all country folk do and I shut my dent off. After the bs'in was done I turned the key to start her up agin and it just cranked over once or twice like the batterie was dead. I'm thinkin how could this be? I shut the truck off for 5min and took the key out, there's no way the batterie is dead! I tried it two more times, still nuthin. At this point I started to louse faith in my ford when my buddy sakes if she need some duramax power I said hell no, turned the key one more time and she roared to life! I drove her home and parked her in the shop. I turned the key agin right after I shut it off and same problem. I came back 24 hours later and tried it agin she started, shut it off and tried it agin same problem. This same problem has happened to me all week. She starts after 24 hours, you take her for a drive then shut her off and try it agin and she don't start. Can anyone tell me what's going on? Thanks

first thing to check is your battery post cables. Clean them off and tighten them but don't over tighten. If they are loose that could be part of the problem. Next thing on the list is to get the battery load checked...autozone does it for free. could be a cell in the battery going out. after that check your solenoid.

How do I tell if I have duraspark?
The posts are cleaned and are decently tight, I will take it to autozone this weekend. I just replaced the solenoid a couple weeks ago so it can't be that. It's got be the batterie, how can I check the alternator?

Do you have points or not ? If you have points and turn it off but key is still on you will damage the points ..

Are the connectors on the solenoid clean?
Autozone can also test the alternator.
It can damage the points..

@devino246
Are you saying that damaged points won't cause starting problems?
When you change the point gap, the dwell changes and so does timing ..
That is what is happening in the case of a points ignition when the ignition is left on the points begin to fuse and the point gap is changed .. Hard or no starting can be expected when this occurs ..
That wouldn't cause cranking problems, though.

The timing would not become randomly advanced if the dwell changed by points fusing .. The timing would have changed for that reason .. It's all speculation until we know whether he has points or not .. It was my judgement that's why Numbersdummy raised the question in the first place because it could have come either way .. What I saw was somebody sitting there in a country BS session not knowing they had a points ignition with the truck motor turned off with the ignition switch still on with no symptoms prior to that moment .. So until we know no points I won't rule it out

So, to the OP: next time you have starting problems, pull the coil wire off and try cranking. If the problem still persists, it's in the starter circuit.

There is a metal box on the driverside inner fender that is about a 4" by 4" square and has 3 or 4 fins on the right side of the box. Would this be the duraspark box? I have not touched the distributor.
