bringing a 301a back to life for a friend of mine. having electrical issues. alternator not charging. it appears to be a prestolite alternator. not real familiar with this critter. heres what i have. with the battery hooked up and key off, both the oil pressure lamp and the charging lamp are lit. on but not super bright. turn key to on position, charge lamp goes out, oil lamp gets very bright. heres a couple pics.
if you disconnect the oil pressure sender wire from the sender, both lamps go out with the key on or off.
the sender is a green wire coming out of the harness that has the end spliced on it. heres a pic
on to the alternator. not sure if any of the wires are hooked correctly, as none of the terminals are marked. it is a jd reman alternator. there are 5 terminals on the alternator. the 12 oclock terminal is a blade type connection. at 3 oclock, 5 oclock 7 oclock , and 9 oclock are post terminal connections. the battery hot is hooked to the 7 oclock terminal. when hooked up, the 9 oclock terminal becomes hot, and the wire hooked to it powers up the two dash lamps. disconnecting it shut off power to the lamps. the 3 oclock terminal is hooked up, but not the 5 oclock terminal. neither 3 or 5 have power when the battery is hooked up. all the post terminals are the same size. heres a pic.
nothing under the dash seems to be butchered or spliced
there is one extra wire that is not hooked to anything, but seems to long for the alternator harness. the tractor does not have any lights on it.
any one know what the identity is for the terminals on the alternator so i can trace the wires back? or any ideas as to whats going on? tia

Today's Featured Article - A Cautionary Tale - by Ian Minshull. In the early 1950s my father bought an Allis Chalmers B and I used it for all the row crop work with the mangolds and potatoes, rolling and the haymaking on our farm. The farm and the Allis were sold and I have spent a lifetime working on farms throughout the country. I promised myself that one day I would own an Allis. That time event
