Hi I have 1992 C2500 Silverado 350,
I replaced the battery with a brand new one today, now when i turn the key it doesn’t turn over
I've been assuming everything "worked" before and @Kevin99 replaced the battery because he determined it was failing.
If my assumption is correct, then other discussions are probably irrelevant... "solenoid", etc. The attendant problems he's having are likely related to what got changed, i.e., the battery and the connections to it.
I've suggested he measure the voltages under load to determine if there's a high-resistance ("poor") connection between the battery cable's connectors (which often oxidize) and the battery terminals.
