Sir,

I have been browsing Yesterday Tractor and HPOCA and noticed that you seem to be in the know of Oliver.  In Yesterday Tractor your knowledge of wiring is extensive and I need your knowledge and help.  My 550 wiring is a mess and I am trying to rewire it, but like everyone else I am trying to get a wiring diagram.  Do you have such a diagram?

I have a 1963 Gas 550 Oliver w/ Generator negative ground.

Can you help.
Thank you,
Harlen L. Jones
