If it has sat, it may have lost it's rotor residual magnetism. Disconnect the rotor field wires at the AVR or on the exciter/brushes. Note they are polaroty sensitive. Connect a 12V battery to F+ and F- (note polarity) and momentarilly power from the battery for a few seconds. DO NOT forget to disconnect the rotor/exciter field wires first or the voltage regulator will be damaged. If it hasn't sat check voltage regulator, rotor resistance, and stator resistance, and for shorts to ground.

Precisely because it is a very old, round type device

If the lights are on a separate switch then yes. If the motor and lights get power from the same circuit, then no. The motor cannot be run on a light dimmer for long before it will burn out. Installing an aftermarket remote control will solve the problem.

I would test the coil by removing it from the circuit, and attaching a properly gapped spark plug to the secondary, then apply and un-apply 12 volts to the primary. If you get a good strong spark on the spark plug tip each time you apply or remove the 12V, then you know that the coil is OK. This doesn't give you a measurement, but you don't know what the voltage is supposed to be anyway.
You might also try measuring the resistance across the primary and across the secondary and compare these numbers to a known good coil (anything similar should be in the same ballpark). Make sure to do that with the coil removed from any other connections and short the terminals together to remove any residual charge before you try to measure the resistance.
I hope this helps, good luck Al K

hi is this error 1505 to remind that a service is due ? and if so this has to be emitted into the program that the service has been carried out .

Try shooting some starting fluid into the intake and see if it takes off, Ive got a mower I have to do that with every spring, runs fine after that but the next spring its the same thing.

hiya for a manual for you here

hope this helps

According to page 64-65 of the 350 !! page manual in this link - "1600" says you have overloaded the generator. "1603" says it only applies to 8kw models and the generator is overloaded. I'm guessing from the limited info you gave that this is an Evolution generator. See if reducing your load makes the error disappear even if you don't have the Evolution model. http://www.generator-parts.com/manuals/home-standby/...

connect the red wire to white,black to black,black to blue, white to yellow.

It means the engine controller has lost the ability to detect the engine speed. Check the mag pickup, and wiring

You most likely have a fuel problem. Either not enough or too much pressure. What fuel are you using, propane or natural gas?
