My starter seems to be working now but I’m having other electrical issues, 18 volts of electrical issues
sounds like a failed 12si, or cs130 (depends on which yours had, i forgot) replace the alternator assuming your sense wire and wiring for alt is proper.
If the sense wire is wired somewhere with a LOT of resistance, it will crank up to make that point get 13.5 ish volts while running, whihc may be 18 elsewhere. Thats why grounds and clean connections are important
Also, you have a 4x4 right? I feel like this was a 78 k10?
Jay, you replaced , as you had declared knowingly., you are replacing 2 of
3 drive train mounts. The transfer case mount is clapped and your shudder is chuggle basically if you knew what that is in a modern trans(auto)
If its 2wd, then same concept but also carrier bearing added
