Default 82 gpz750r1 knacked?

Finally got ma zed into dry storage......connected a car battery on and no joy.Got a neutral light and oil pressure light but nothin at starter motor,voltage is gettin to the input side of the solenoid but as I only have a basic needle type volt meter my trail ends there.Only other thing I have noticed is that when you pull in the clutch lever the lights on dash,sorry,clocks dim down.Was thinkin clutch interlock???Now sees the wisdom of dry storin a bike to restore,lol.

Cactus, how long ago was the bike running? if the engine has not turned over for (gasp) a few years, I would begin by pulling the plugs and shooting some penetrant into the cylinders. Let sit. Don't cook your starter or snap any internals trying to bump start.

yup yup yup on squirting some penetrating oil into the cylinders to help free up the possible rusted piston rings in the cylinder. then after sitting a day, hand turn the engine so you can feel what is happening, less chance of snapping rings, and frying stuff as jeff mentioned. I used diesel in the past, but not sure if I would use that anymore because of the NEW STUFF

Electrical wise, the grounds and other connections are probably all corroded. Clean connections and use electrical cleaner for small contacts. Even the ignition switch.

You have some work ahead of you, but nothing too serious probably now that it is in dry storage. Takes a little time.

Tried turning engine over and it turns by spanner on the alernator nut no probs.There is 12v getting to the input side of the starter solenoid however nowt happens when you press the starter button.Cleaned all earths and had switches apart on bars but no joy,think i need to try a new solenoid however im using a car battery to try the electrics out and i did use a bike battery last time.

Is the starter "frozen" also? Might double-check before you toast resistors in the new solenoid.

No,ive got 12v going to the solenoid by fuse box but nowt from other side to the starter.I put a direct 12v onto the output side of the solenoid and the starter did try to turn the engine but as its a direct feed I didnt like to leave it on for more than a second or two.Engines easy enough to turn over on the alternator nut by using a 1/2" drive tbar n 17mm socket.
