Oliver 1655 diesel. 12 volt system in parallel two batteries.
Have been monkeying with electrical system to get it working right.
So far so good.
Idiot light installed, alternator charging battery after start, ammeter comes back to just above 0 after a few minutes.
Manifold heater is the question.
Thought it wasn t working, as pressing button makes solenoid click but no draw on ammeter while holding button.
However it sure feels nice and hot to touch after a long 30 second press.
Any ideas why a large load like that wouldn t show up on ammeter?
Battery goes to starter, starter goes to ammeter, starter goes to manifold heater.
Flick on headlamps and that shows a draw on ammeter (engine off)
Press heater button nothing shows.
Lights go through ignition and ignition powered thru ammeter
I prob don t understand electricity.
I assumed if the heater pulled juice from battery by way of starter post, that would show up on ammeter.
As ammeter is wired on one side to starter post as well..
However perhaps the manifold heater bypasses the ammeter? Does it just suck juice from battery to starter post to heater and the ammeter would have no way of knowing current was flowing from Battery.

Today's Featured Article - Restoring a John Deere 2010 Diesel Tractor - by Jim Nielsen. Following seven years working in California's Silicon Valley, my wife, baby son and I moved back to Australia to retire. We bought a small 'farm' of about 50 acres near Bendigo, in the state of Victoria. I soon found that it would be very useful to have a tractor around the place for things such as grading our long drive and brush-hogging the fields. I was also embarking on planting 1000 eucalyptus trees, and hence I would need a ripper, small disk plow, sprayer etc. to get these things accompli
