Rinsed off the 318 yesterday, didn't take the side panels off. Hosed off the top of the engine, battery and prob got water all over the wiring and TDC. Tractor was running at the time. Now I have a battery light on and 12.3v at the batt terminals at idle, and 11.9v at WOT, so that tells me the batt light ain't lying. Left the tractor inside my 90 degree garage all night hoping that would dry it out, didn't help. Where should I start?

Voltage regulator terminals, key switch terminals and the TDC. I'd just remove and let hang to let dry, might take a couple of days. Harbor Freight sells a heat gun but gee whiz it can get things really hot if your not careful.

According to the wiring diagram for for the Honda. Two gray wires come from the charge coil, and I don't have any voltage there at all. Guess I'll give a couple days and check it again. I can't imagine water getting under the flywheel and causing problems.

The voltage from those gray wire are probably AC.
Did you try with your meter on the AC range?
I always clean mine, also with a 24 Honda with a hose like you did and never had this kink of problem.

I was hoping you'd chime in Andre.

I thought they were probably AC, but I checked them with the meter set both ways just in case. They also show a completed circut when you check the ohm's, not sure if that should be the case or not. I'm assuming the GX670's that SEW was selling have the 20a coils in them.

Philip,
I don't have he shop manual but I found something for a 3A and a 20A.
For the 3A the rectifier have 3 wires
For the 20A the rectifier have 6 wires

I used to have problems like this until I had to trace down a rusted wire connection. I have been using a 110volt leaf blower since then and have had no problems! Try it.

Philip,
I found someone with a similar problem and few test to do:

Yep, saw that thread when I searched google. Started it up this evening, same thing, no voltage out of the charge coil wires at all. Looks like I'm pulling an engine.

firewall insulation time? Engine out?

Clean all the terminals, you can get some electrical connection cleaner spray to clean them and then Blow them out with high pressure air nozzle I would put die-electric grease on them. Then plug back in and see what happens.

This is the 20-21 Hp Honda? They have more than a 3 amp output. The one on my mini-dozer had a multi pin plug that went to the regulator and plugged into it.

 

[pinmd]

Bill, this is the GX670 24hp Honda, and yes, it has the 20amp coil/multi pin connector. The two gray wires in that connector run down to the bottom front of the engine behind the pto, then they connect to two identical gray wires that come off the coil. I disconnected them at this spot and checked the AC voltage there. Got zilch. All I need is some time and energy and I'll pull it out and pull the flywheel to see what's going on.

Hi: There is one thing to check. I installed a new Honda GX630 in my JD316 just last may. When complete I had no charge. Turned out I had not connected the (I'm in AZ and my tractor is in MN so this is off the top of my head) black with yellow striped wire from the voltage regulator to I think the ignition circuit. I may be wrong about where it went or the colors. Anyway, check your wiring from the regulator to each terminal. This may be where your problem lies.

 

[wmgeorge]

Phil, When you check those two gray wires with your ohmmeter what do you get for resistance? Yes they should be showing some sort of reading. If you check either wire to ground, and don't put your fingers on the meter leads, you should be getting really high resistance or nothing at all to ground. Depends on how good your meter is.
I've dealt with electric since 1962 so I know my way around a Fluke

.
I find it hard to believe your internal wiring is screwed up, the regulator maybe. I have a downloaded manual someplace for the engine on my mini dozer, let me do some checking....

 

[wmgeorge]

Yes it shows the 2 Gray wires coming out and going to the regulator. Check them with a ohmmeter like above, you should be getting AC or at least pulsating DC out when the engine is turning over with the starter.
What meter are you using?
