Suzuki: 1987 Suzuki Samuari reverse batt. hookup, blown fuse, battery cables

Question
Put battery cables on in reverse: fuse(s) or ? popped (saw one smoke). Now it won't start - nothing at all when turn key. Checked main fuses all are good. Need to know where to look from here. ECM knocked out? (Hope not:(

Thanks

Answer
Probably didn't hurt ecm unless you turned the key on with connections backwards, and then only maybe.  It's strictly a matter of connections.
You may have a blown fusible link (a wire at the battery that is in fact a fuse device)
First check at the starter and see if the big battery wire has power.
Then turn key with clutch depressed and see if the smaller spade connector at the starter has power.  Marginal (corroded) connections at the battery are pretty common.
You can check at the ignition switch to see if there's battery p[ower, and if the starter circuit is energized.  While it's not common, clutch switches have been known to fail.
In short, the starter circuit is separate from the ecm, and you most likely have a bad connection, blown fusible link, or blown fuse that you're not aware of - yet.
I keep telling everyone - look online, there are free online downloads of the factory manual complete with accurate wiring diagrams for your year vehicle - It's really worth the effort.
Don't hesitate to ask again if you need additional help or whatever.
