#Accurate 4 305 chevy starter install#
Solution #1: Due to variances in design between manufacturers, you may need to install or remove starter shims between the starter mounting block and engine. Problem: Starter does not engage or disengage properly. Otherwise, the engine will turn over slowly. Engines with 11:1 or higher compression generally require a high-torque, gear-reduction starter. Solution #6: Confirm that you purchased a starter designed to work with your engine’s compression ratio. If it turns over with the key, the switch is either bad or wired incorrectly. You can check by attaching a jumper wire between the safety switch terminal and the main terminal on the starter. If this switch is bad or not properly wired, the starter will not operate correctly. Solution #5: If your vehicle has a neutral safety switch, make sure it is operational. Most starters are grounded through the mounting block, and if there is excessive oil or paint on the block, the starter will have a faulty ground. Solution #4: Clean the starter mounting surface. Bad cables will not deliver the full current flow needed operate the starter.
Solution #3: Check your battery cables and make sure they are in good shape. Most starters require at least 9.6 volts to turn over correctly. Solution #2: Check your battery voltage and make sure it is sufficient to turn your new starter. Often, the starter is misdiagnosed as the culprit for electrical system problems when the problem really lies in some other area of the system. Solution #1: Check the rest of the electrical system for the correct voltage, grounds, and wiring. Problem: Starter does not turn or turns over slowly when key is turned. You’ll find that you can diagnose and fix many new starter-related issues right in your home garage.
That’s why we’ve worked with the tech advisors at Summit Racing to put together this quick guide to troubleshooting starters. We don’t wish that on anyone, especially after you’ve spent part of your weekend installing the new starter. What’s more frustrating than an old, worn out starter that just won’t turn over? How about a brand new starter that won’t crank over…or engage properly…or fit correctly?
