When I tried to start the engine motor would not turn over. Also no power to radio, power windows. Tried turning key back and still no interior power. Battery is good. What do I check?
No power when turning the key

Check the terminal marked Batt on the bottom of the fuse box. If now power it could be the bulkhead connector or fusible link. Be sure to check battery ground too.
If you have power there. Check the red wire in the connector under the column. Both side of the connector.
With the key on. There should be power at the black wire
Accesses.

Follow the dots. Understand how it's wired first. Blue charge circuit, yellow battery supply, red ACC circuit. Headlight sw is feed from splice one under dash.
One word explains the wiring and connections. Inadequate! Read Description and follow the dots. The wiring is not heavy enough and the connection were not designed to carry that much amperage 1:RED wire 16 Battery power yellow dot to splice one feeds fuse block, 2:charge wire 18 black wire blue dots to splice one through amp meter to red wire blue dot 16 to battery, 3:ACC feed from splice 1 Red wire Q3_12R yellow dot to steering column. Black wire 12BK red dot to ACC side of fuse box.ch load. The round back alt has an output of 37 to 45 amps max and the wiring is designed for that.
