    All,
    I am in need of a engine for my Kohler Genset. The engine has a cracked block. Confirmed. The generator portion performs great. I realize that it might be a better decision to just replace with a new unit in warranty but I am on recon at this time.
    Here are the facts :
    1984 Carver 3607 Aft
    Original Genset
    Kohler 7.5 R27
    4 Cylinder Gas Engine (Flathead)
    I am told that these Engines were built by Ford. (Not Confirmed)
    Any information or contacts would be appreciated.
    Thanks in advance to all.

    start relay

    hello everyone - I have a Kohler genset 40 EOZD, 2007. When I go to start, I hear a few clicks, then get an overcrank alarm. I have checked all the fuses in the controller, The solonoid seems good, but I can't locate the relay. Any suggestions would be helpfull.

    Need Wiring Diagram

    Buy an engine manual with wiring diagram and make available. From the Parts Diagram, I find 3 relays for Start: #2 a hvy duty Crank Relay, #40 small Starter Relay (may be in Control Box), and #5 starter mounted hvy duty solinoid. Most likely the small relay powers relay 2 which feeds the starter motor when starter solinoid closed. Test starter and solinoid by putting 12v (or 24 if 24v) to starter solinoid (small terminal on starter). It should engage the starter. If so, relay 2 and 40 get inspected. Your relays in the Control Box may have LEDs that can assist in analysis.

    The flat head Fords were built by Ford and used extensively in tractors, for years. If you join a Ford tractor discussion group, you may find exactly what you're looking for. Try and get the engine numbers from the block first so you can compare apples to apples. Good Luck with this.
