I’ve had this thing for about two months now, the guy I bought it off of claimed he replaced the starter and when I went underneath today, it looked new (not caked in oil or rust). It was a quick look at the terminals and wire brushed it till it looked shiny, I can probably deep clean them tomorrow. I’m also gonna try to pull my frame rail battery out tomorrow and plop it into the engine bay and see if that changes anything. Also noticed one of my wires to the frame battery terminal was really loose so that might be a part of my issue.

OK…be careful with those positive cables on the starter….undo the positive up top…and if you can’t get to the frame battery, the negative…on mine anyway…is onto one of or by the starter bolts…undo that…then you can SAFELY REMOVE the hot wires at the starter solenoid…clean well and reinstall…
next…frame mount battery…maybe you know but in case you don’t…4 bolts hold the case on to the frame ….3 of them just need to be loosened a couple, 5 turns or so….BUT the top right bolt needs to come out completely…the battery case than slides towards the front and then lifts off…it hangs on those small cables…I slide under on my back and then “bench press” the case…it has 2 handles for this…I disconnect all power as previously discussed cause the case is metal and rarely are the battery hold downs used…

Sorry about disappearing like that, found my problem and turns out it was a mistake by the previous owner. So turns out the guy wired the starter solenoid wrong along with not tightening one of the nuts. I put the wires where they were supposed to go and tightened up both nuts. Went into the cab and turned the key and I had power, cranked it and it fired. I’ll probably still take a look at the second battery but I need some more resources before I go down there. But thank you for all the advice was given, I’m going to be slowly going through the spaghetti mess of this van over the next few months.
