1. TURN OFF THE CAPS LOCK. 2. Innova sells consumer-grade junk. Apparently, they have morons working the Tech Line, too. Can you take it back to where you bought it for a refund? GM suggests the Tech 2 for my '92 and '93 Luminas. I'd think the Tech 1 would be too old. 3. No such thing as OBD 1.5. There's OBD-2, and "pre-OBD-2" which became OBD1 by default. Any decent scan tool that has the correct software and connectors to suit the vehicle should work. If it won't connect to the vehicle, either you don't have the right software, or the right adapter(s), or the scan tool is consumer-grade trash. 4. I spent 20 years working with a Snap-On MTG2500 I bought used off of eBay (MT2500 similar, less expensive, more common) and when that died about six months ago, I got another, newer Snap-On scan tool, again used on eBay. Pawn shops, and Craigslist are other sources for scan tools. I bought a Snap-On Solus Pro, $350 shipped to my door with software suitable for 1980 1/2--2007 (Version 8.2) a battery with some life in it, and a charger, a bunch of OBD1 vehicle adapters, an OBD2 adapter with personality keys, operator's manuals on DVD, some power cords, and a bigass suitcase to carry it around in. My Solus Pro was made in 2008; it's no spring chicken. Snap-On no longer supports the '2500s, Solus, Solus Pro; support for the Solus Ultra either just ended or is about to. Solus Edge and Solus Legend can still be updated--but the Ultra, Edge, and Legend (current model) are also way more expensive. 5. I would MUCH rather have a used-but-usable Professional-grade scan tool than a brand-new consumer-grade tool. 6. A "real" scan tool communicates with every on-board computer-controlled system on the vehicle. Newer vehicles have more computers/modules that can interact with the scan tool than older vehicles. Depending on the vehicle I've got the scan tool connected to, I can get codes and data, and perform certain diagnostic tests with the engine, transmission, ABS, air bags, instrument cluster, and body module (door locks, wipers, HVAC, etc.) 7. Stop replacing parts, start diagnosing problems. Sounds like alternator/wire harness issues to me, but that may not be the only thing(s) wrong.
