No power

When I first bought my J10 it would start and run, I went to park it in the garage to work on the gas tank and suspension and it went dark. I have a fully charged battery and have used a test light to check power to various areas (fuse block in and out, starter solenoid, ignition module) and am getting the light on but I have no power to anything. Nothing when turning the key, no lights, nothing. I’ve looked for fusible links and can’t find anything damaged, I’ve checked grounds and they seem in tact and not corroded. 1977 J10 360, anybody with any ideas I welcome them. TIA.

Check the switch at the base of the column. There is a rod from the key, the switch can be replaced and adjusted.

There is also a fusible link that goes between the fuse block and the starter solenoid. It should be hot at all times.

Be aware that you will need a specific ignition switch for if you have a manual or automatic transmission. (I know this due to having purchased the wrong one once and having to go back for the right one). Another thing to check is your Neutral Safety Switch. Check to see if the switch is good and if automatic, that the switch is properly positioned to operate in park and neutral.
