Starting a motor on the hard.

[Joe4711]

I am trying to start my 140 Johnson on the shop floor, but things are not working.

1) the starter sometimes kick in and will not release from the flywheel, causes mad dash to get batery disconected,( does not do this all the time)

2)The key is not wired to the motor at present, some one cut the wires.

3) I assume there must be some cut off/ kill switch on the motor that I can bridge to kill the motor when I want to, I guess this switch is currently in the off position as there is no spark from the coils to the plugs.

4)I have searched the site but can not find a answer I am sure this has been talked to death before. My workshop manual also assume the motor is on the boat with wiring intact and everything in pristine condition.

5) The guy I bought the motor from had no problems in starting it to demo it to me, but is currently out of town, so that doesn't help.

Help please,

Tx,
Joe.

Re: Starting a motor on the hard.

OK,
I realise from my post I probably don't sound like the brightest candle in the box but even I am not daft enough to try and start a motor lying on the ground.

The motor is on a cradle with a battery and water muffs attatched in the proper way ( there is even water flowing thrue the hose connected to the ear muffs)

Now how about some wireing connection suggestions or directly answering the questions I ask.

Tx,
Joe.

Re: Starting a motor on the hard.

install the battery cables, as you normally would in the boat. the jump the solenoid. or use a remote starter switch available at any auto parts store.

90% of starter problems are bad connections. remove and clean both ends of the battery cables, so that they are shiney, also the cable from the solenoid to starter. check for nicks in the cables. and make sure the connectors are on the wire good. the cable tend to corrode from the inside out, if nicked, corroded wires, and connections, heat up and cause resistance to the follow of electricity, thus the starter doesn't get enough. you can also take jumper cable pos battery post to large post on starter. with a good connection, the engine should spin. then if the starter is good clean everything and retest. then trouble shoot solenoid. starters can be rebuit at a starter/alternator shop, much cheaper than a new one.

also have the battery load tested at the auto parts store, free, i've had new batteries go bad

Re: Starting a motor on the hard.

Inspect the flywheel gear teeth, they should be relativly smooth. If you find burrs take a small file and clean both sides of each tooth and the lower edge of the slot where the starter pinion enters. I actually paint a very light coat of moly based grease on the teeth. Makes them very quiet and resists getting stuck. Check where the starter bolts to the engine, make sure there are no loose fasteners and that it sits flat against the mounting boss.
Follow TD's instructions on the hook up and you should be able to make smoke with that engine.
Stay away from the PROP while running!

Re: Starting a motor on the hard.

Thanks for the help so far.

I connected the wiring to the control box where it was cut off, choke solenoid is working, starter turns motor at full speed but there is no spark on any of the cylinders.

Is there a kill/cutoff switch somewhere or how could I check power to the coils without the flourescent tester as described in the manual.

Thanks,
Joe.

Re: Starting a motor on the hard.

The kill wire is black with a yellow tracer and runs to the powerpack. It functions by grounding the powerpack from the ignition switch, but is not closed if the large red harness plug is disconnected at the engine.

When the motor is running, grounding the black yellow wire at the block will instantly stop the engine.

BTW, Any voltage riding the black and yellow wire will destroy the powerpack(s) and that will stop the engine as well.

You can get a good read on the wiring here: http://continuouswave.com/whaler/reference/ignitionSwitch.html
