I replaced the ignition switch on my 98 Rodeo. At first it started but wouldn’t idle. Then it would start but idle at 1000 instead of its usual 600. Then nothing. No power anywhere. Battery is good. Ideas? Thanks

Did you disconnect the battery to change the switch? If you did, disconnect it again, both terminals, and clean both battery terminals with a brush made for the purpose, and also clean the terminals on the cables with the other end of the tool.if you didn’t disconnect, you may have blown a high amperage main fuse near the fusebox or a fusible link. If those are good, recheck your work.

See if the main fuse 100 amp in the fuse box under the hood had blown.

100A and 60A fuses are good. Battery tested and it’s good too. Terminals cleaned and connections tightened. Any ideas?  
Thanks
