DK40 Charging issue.

I'm glad that you tracked it down but, it doesn't completely explain all the glitches that you previously mentioned, especially the second ignition switch replacement and why a battery would be dragged down to 6 volts in a short period of time (assuming no lights in use). Please inform if this turns out to be a Red Herring..Mike.

I think it does explain all:

1. The original ignition switch was faulty in another respect;
2. The original battery was about 10 years old is was proven to be past it's life;
3. When a battery is not being recharged and is driving an agricultural spray pump (12V) it doesn't take very long to drain. Lights must be on for the pump to work (connected to 7-pin plug), which is no issue provided the battery is being charged.

With an intermittant fault we sometimes make assumptions... such as a faulty alternator, faulty battery... (blame the battery salesman of course... lol). Now I have a perfectly good spare alternator.

Will keep you informed if I got it wrong.

Ignition switches are an issue. I had problems with mine not starting. Completely dead. No clicks at all. After some investigation it was the switch so I replaced it. It was an easy fix. Now I have had the new switch 2 years. The tractor sees no wet weather to speak of and is kept inside. The new switch started acting up just a couple of weeks ago. So I sprayed a penetrating fluid in twice and the switch worked fine. So, poor design I would say.
