Default What are the signs of a bad starter?

I couldn't get my engine cranked yesterday. It started immediately on the muffs a week ago. When you turn the key, the starter spins, pauses, spins, pauses, spins, pauses, etc.... It spins the flywheel about 3/4 of a turn. Is the starter going bad? It did the same thing on the muffs, but after about three 3/4 spins, it sped up and the engine caught. I see plenty of new starters on ebay for around a hundred bucks and I shouldn't have any problem putting it on, but I don't want to get a new one and find out that's just how these older motors crank.

BTW, it's an '87 Johnson 90

Sounds like possibly a loose connection or even a bad battery. Is it possible something drainded down the battery whileit was sitting?

Sounds like an insufficient battery power problem to me. (not that I know anything...)

check your connections first of all, take them all loose and clean them and hook everything back up, this is the most likely problem. If this isn't it, most likely it's a battery issue. as far as starter pricing goes, 100 bucks isn't bad at all for those, they normally sale for around 85 bucks wholesale within the reman industry (which is what my father does).

1) Double check all your connections... make sure they're all clean and tight.

2) Double check that your battery is full and works properly. (Easiest way is to hook up a pair of battery cables to another fresh battery)

3) Listen to make sure the solenoid is clicking and trying to engage the starter and start the engine.

4) If you're still having the same symptoms as originally, you need a new starter.

ps. Before trying to remove the old starter, make SURE you disconnect the battery... I almost zapped the heck out of myself changing my Jeep's starter last week when I forgot to do this, and inadvertently made a connection between a hot wire and the chassis.

Before you yank that starter, make sure your battery is as HOT as you can get it AND all your connections are solid...usually a bad starter just won't turn at all... ...

This is why I frequent this site. I'll check and clean the connections, charge the battery and see if it'll work. Thanks.

oh, one other thing, if you try everything and nothing works, try to take the starter appart and clean the contacts on the solenoid with emery cloth, as this is a common problem, while you are in there, may as well polish up the stator (brass end, not the wires).

You should also inspect and clean cables and terminals from solenoid to starter and battery ground cable on engine If cranking continues to be erratic after cleaning all terminals and lugs check the battery cables and cables terminal lug crimps. Pull the cables from the boat and run the entire length of the cable through a closed hand; good cables will be flexible along the entire length and cable diameter consistent, internally corroded cables will be stiff and/or "bulge" at insulation or terminal lug where corrosion sets in. Corroded cables may show good voltage (12.6 volts +or-) when battery is charged with engine off but charging voltage while running (typically 13.8-14.2 volts +or-) will be lower than normal and repeated starting will eventually drain the battery and cause the symptoms you describe.

Doesn't sound like the problem you are having but can't hurt, these starters get "sticky" on the worm gear that the starter gear travels on. I spray mine at the beginning of the year with a good light lubricant and work it up and down a few times with my fingers. As others have stated your problem sounds like a bad connection or low battery. Usually when these starters go bad they won't spin at all.

Only way to check a starter is to hook up an amp meter and measure draw when cranking the engine. Poor starter pulls high amps.

Check connections, and if you have one the battery switch.

As mentioned watching amps is a good method. Just be careful, many cheap clamp meters don’t read DC amps, or are slow and have a hard time reading momentary loads.
