Reply To: Trouble shooting a starter

[Gregory Long]

I will highly suggest you make an additional ground cable from the + post over the transmission, and install the soldered-on loop under one of the 3 starter mounting bolts. If properly routed, the additional cable is not noticeable.

The reason for this is that the original ground cable attaches to the right side steel frame rail. The engine mounts are riveted onto the frame, the engine is then bolted to the frame mount. The starter is then bolted to the engine. With each of these connections, there is inevitably some corrosion, loose or partial electrical connectivity. The result is poor current carrying ability.

Installing a stand-alone battery-to-starter ground cable usually results in a NOTICEABLY faster cranking speed.

Once you have established a good, high-current capable electrical supply, then see if the starter cranks the engine. Usually the commutator is coated in oil, or the brushes are worn, or hanging up [sticking] in their guides.

Let us know how the repairs progress.
