    get a electrical tester and check for a hot lead wire for the positive side of the alternater,then check for the hot wire for the ignition ,you will have to turn the ignition switch on for the hot wire that plugs in the side of the alternator

There are no free full diagrams on the net, you need to charge and test the battery, clean the battery cables and run a voltage drop test as well, replace them if the are badly corroded. Kragen will test the battery for free.

You only have a few choices. Buy a repair manual at a parts store. Go online and google wiring for your truck and you might find it posted for free. Go to Alldata .com and pay for the info you need or ask nicely at a repair shop or dealer that can print off the required info.

SOURCE: how to hook up the wiring on a 1997 chevy blazer

Hey how ya doin! underneath the rear of your blazer on the drivers side you will see some wiring running by the frame rail tword the back bumper. about 8 inches or so up the harness you will see a large clip holding it together. You just unhook this, go to your local auto store and buy the harness clip that clips inbetween these two connections. Poof instant trailer lights. The harness you need to buy is around 20 bucks and its a cinch to put in. Even if you dont quite understand what I am saying here, once you buy the piece and look under your blazer, you will see just what I am talking about. The only catch is the boughten harness only comes for the standard four point hook up. If you need the big round rv style plug you will have to adapt up to it. These adapters cost another 25 to 30 bucks. Hope this helps. Later, Clay

My 1997 chevy blazer if sits for a period of time drains the battery. why? and when i took it to my mechanic his computor analizer could not comunicate with my blazer. why?

have a load test done on the battery to check for internal failure. remove the battery earth wire and fit an amp meter in the line to see what amps are flowing when everything is switched off. It could be a faulty diode in the alternator, boot/ glove box light staying on, interior light on or a faulty relay or module./ As to the scanner not reading the ECM records , there are several different leads that are in use for different vehicles so make sure that the correct sequence is being used to get readings.

My Headlights are so dim that I cant drive at night in my 1997 Chevy Blazer. How Can I get them brighter?

You have to go back to the route cause & time
frame of the problem

Did you check voltage & ground at each lamp connector,
when they first got dim & you started to resolve things?

Why converter to a different bulb?
I don't know the current draw of the oe vs: the H4,but
that has to be considered

Obviously the alternator output would be up there at the
same time your checking lamp connector voltage.

Problem--Voltage Drop somewhere or too much resistance
somewhere,basic OHM's Law

There are a few schematics. Dash Wiring, Whole Vehicle wiring, and fuse schematic for example. All are provided by a dealership for free. Some ask for a quarter per page print out at the most in my experience.
