B6000 charging problem/headlights

[Brock2435]

I am in the process of restoring my B6000dt and am having an issue with the battery not keeping a charge. I know that either the rectifier or the dynamo is bad. I am not sure how to test those to see if they are working or not. Also, I am not sure what kind of headlights I am able to put in the tractor. Was really hoping to try and put LEDs in but if that doesn't work what would be the best bulb?

Find the two leads that come off the dyno - get a set of alligator clips and attach them to those leads and place those clip on your multimeter SET TO AC.

Start engine and rev up to 3/4 WOT - and tell us what your reading is in AC - if you got something like 25-30 volts AC - the dyno is good.

If that passes the test - reconnect leads and now place multimeter on DC and place the + and - on the battery - should have 12.5 ish volts DC - start engine, and rev up again - should rise to close to 14 volts DC.

IF the DC volts do NOT increase - chances are you have a bad rectifier.

AS for lights - IF you can get a 14 volt DC - any LED lights will work fine, unless you plan on putting many lights on the tractor. Most LED will draw an AMP or 2 depending on the amount of bulbs in the LED housing.

Forum member Lugbolt put together a page of diagnostic instructions re dynamo/rectifier.
What 85Hokie has told you is similar.

Also, be sure to remove battery and confirm it WILL take a charge, say with a regular battery charger.

Does it matter which two lines I pick coming out from the dynamo. There are three wires.
