need help with yamaha 81 maxim
« on: August 10, 2009, 06:46:41 PM »
so i just spent 2 months polishing, painting, disassembling and reassembling then more polishing... but now the starter doesnt turn.... when reassembling the wire harness i found all the right connections (matched plugs and wire color) except 2 one was a blue and i plugged a ligth blue lead to it and one was a single white lead from the engine that i plugged into a black wire with a red stripe... i looked through all my parts and all over the internet for some wiring help and had to guess at these two leads... when i hooked up the battery and sprayed some starting fluid in her she turned right over and ran for 3 seconds... and stalled so i hit the start button and tried to turn her back over and she acted as if the battery was dying slowly turning and then stopped.... so i charged the battery and tried this morning and nothing i tried to bump start her and nothing..... i did notice the oil light comes on when the start button is pushed so.... help please.....

  You have a hot wire touching a ground somewhere. EVERY connection needs double checking. Feel around for a wire getting hot when key is on and when hitting starter button. Disconnect signals, lights, horn, signal relay, gauge lights (oil pressure light and lead as well) and see what happens. Also battery hot lead ans starter solenoid needs checking for touching something.
  Recently a buddy's Suzuki Intruder wouldn't start or crank. I asked him what he did so far; he replaced the battery and the starter solenoid. After much digging around and head-scratching (I'd stop-by and poke around several times over the course of it sitting unusable in his garage for 3 months. It would not crank and a new starter was the next option), I noticed the nut from the starter solenoid was touching the frame. I simply re-angled it, pressed the starter button and it started right-up. The symptoms included wires to starter getting hot, and wierd clicking/humming sounds instead of starter cranking.
   I owned a 700 Maxim for a while; nice-sounding machine.

could it be the starter relay? i pulled the the direct cable from the starter to the relay and jumped it  to the battery and she turns and will run on starter fluid (when i turn the carbs on the piss out the over flow tube off the airbox).... im not sure if i said above but the oil light comes on while the starter button is on... is this normal for yamahas?

 The oil light comes ON when key turned ON w/o bike running. Oil light goes OFF when bike starts running. If it goes on only when you hit starter button, trace the wire and see where it connects, it has NO connection electrically to starter button; it is activated from oil pressure and has a devoted wire color coded. On Honda's it goes under the motor and connects w/ a phillips screw to rankcase, and goes to gauges.
