Please help katana is dead

[Shaun23a11en]

Hey everyone i have an 82 gs550 katana. When I hook up power to the bike nothing works. Key doesnt work. Shows no signs of life besides the starter switch getting power and the top fuse in the fuse block also gets power but not the bottom three fuses. Can you guys please post pictures of your fuse block area so I can see if all my wires are going in the right place?

Welcome to the site. WHen you say the top fuse is getting power, does it have it on both sides? Use a test light to verify. From there, the circuit goes up to the ignition switch so test for power there as well with and without the key on.

Hello and welcome to the forum.
You will get an official welcome soon.

There are some manuals on a members site he will be by to greet you soon.
Be patient you are in the right place.

What they said. I just wanted to offer to take that 550M off your hands if you are in the KC area. That way you don't have to bother with it.

I've been keeping a lookout for one of those but haven't had much luck.

I used a volt meter. The red power wire on starter switch gets about 13 volts. The fuse block with just one fuse gets power. The top fuse of the four gets power I didnt check both sides I put the meter directly on the body of the fuse. On the fuse block with just one fuse in it there are two philips screws. One positive and one negative. The postive also gets power but it doesnt have a wire going to it? Kinda confused as to where the electrical path is traveling and,where I should be looking? Check the actual ignition switch next I guess right? Is there a connector that comes of the switch or exactly how should I check it? Ive had plenty of old hot rods but this is my first bike sorry for all the questions. Thanks for the welcome everyone

The single fuse block is an accessory block. Check your main fuse - wire coming off the solenoid/battery to it - for power on both sides first. It is possible that fuse has blown and you won't see it. From the main fuse it goes to the ignition switch and kill switch back to the fuse block to power the remaining fuses.

So if that top fuse shows its getting power it may not be bridging the two contacts because the foose is actually bad?

[cowboyup3371]

When you say "top fuse" are you talking about the single one by itself or the main fuse?

The main fuse is the one in the block of 5 fuses where the battery comes into (this could be a feed off the solenoid or straight from the battery). Check that, if you don't see power on both sides of it, it's blown probably under the caps.

Yea ive been talking the main fuse. When I put the meter on the actual metal base of the fuse its showing almost 13 volts. Do I need to check both sides of the fuse or since one side is getting power doesnt that mean the whole fuse is?

To check the fuse you should really check the resistance across the fuse. Set your meter to the ohms setting, usually to 20 range and connect to either side of it. If you get a low ohm rating then its good. If you show OL or infinite resistance or high resistance then the fuse is bad and should be replaced. Ive had fuses go bad that "look" good but are in fact not.

You should test both sides, which will generally tell you if your fuse is blown or not. Feel free to use the ohmmeter, but I'd disconnect the battery first.

The other side of that top fuse heads up to the ignition switch then back to the other 3 fuses. They'll only see power if the ignition key switch is on.

No the fuse could be open, not allowing the other side of the fuse to have voltage..

[Shaun23a11en]

Actually I do remember only seeing power on the left side of the fuse

[cowboyup3371]

Make sure it is the main fuse you are checking. The three other fuses for the horn, starter, and lights will only have power to one side until the ignition switch is turned on.

By the way, do you have a Clymers manual or the factory service manual with the wiring diagram? If not, go to http://members.dslextreme.com/users/bikecliff/ and download it. He'll be along later with the official welcome.

I have been checking the very top fuse that is grouped with the others right below it. It gets power on the left side of fuse but not the ride side with key on or off. The bottom fuses do not get power to any part of the fuse key on or off.
