    Starter issues 1977 fj40

    Keep in mind, the only reason resistors were introduced into ignition systems, was so that they could be bypassed when cranking to make up for the voltage drop. A coil that gets paired with a resistor is designed/wound to run on the lower voltage incurred during cranking. After startup and...

    Looking at a diagram from a Trollhole post , your 1977 had an external resistor and a bypass setup. The starter in the diagram shows the extra contact/terminal for that bypass. It appears in your first pic (post #1) that you do have the starter with that extra contact/terminal. I’ve heard some...

    Ah! I see that now. It looked like a frayed unconnected wire. You measured the rpm difference. Very good! Can't argue those results. I measured the difference in voltage drop while cranking and the GR dropped less. Didn't write it down and can't remember how much, just that it was better.

    This is a little confusing. More pics would help. Pics of the ignition setup (coil distributor ect), a better pic of the terminals and connections on that after market relay, and maybe a straight on shot of the end of the starter. From your original pic (post # 1) it appears you starter has the...

    The motor on the GR turns much higher rpm but with gear reduction, the output design speed is similar to a non-GR starter. However, the output torque on the GR is higher and it does it with less amperage. This higher torque may equated to higher engine starting rpm when considering varying loads...

    The problem with using the #50 terminal for the resistor bypass is,, yes it would bypass the resistor while cranking but after that, you would have resisted voltage back feeding the starter solenoid and also whenever the key is in the “Run” position. It would be the lower resisted voltage back...

    Matt. The starter that came on mine and the spare that came also, only had the battery lug and the one spade terminal. They didn’t have that extra terminal in your pic marked “To Ignition Coil USA” which I assume is for the resistor bypass. The “C terminal” in your pic is confusing. I don’t...

    The main reason I went with the GR starter is that it draws less amps and my thinking is, with a weak battery on the trail, a GR starter could just make the difference between cranking over or not. Lighter and smaller is just a bonus. As for ignition, there are several choices and I’m not...

    Good pic Matt. That's showing the auxiliary contact built in. The starter that was on my rig, when I got it, did not have that extra contact. I added a relay to make the resistor bypass operational. But now it's a GR starter with no auxiliary contact and no resistor with the DUI.

    One possibility is the relay was for a resistor bypass. Some starters had the auxiliary contact for the resistor bypass, but replacement starters often do not have it. When this happens, the bypass will often get done away with unless a relay is added to make the bypass operational.
