Starting issues..Such thing as a weak starter?

[nightrider05]

I have searched and read through many pages, so please forgive me if this issue has been addressed countless times.

I picked up a 94 WB a few weeks back and it started up and ran great(145 psi per cylinder). All of the sudden it would no longer start while riding, got it back to the trailer and started tearing it down. Long story short, all I had was clicking from electrical box. I charged the battery and retried..same thing. Opened box up and jumped solenoid/relay and got absolutely nothing from the starter. Pulled the starter off and hooked it up to a 12v source and it spins...So what could the problem be now? I am sure the motor is not locked up and the motor is getting oil. Could the starter be weak by chance? Any help would be greatly appreciated.

EDIT: Also wanted to add that I did clean/check connections before doing all of this.

EDID 2: was bored so played around a bit more...now the starter will not turn when hooked up to 12v source. I hit it with a wrench and it starts turning, but doesn't seem to have as much torque as most do(usually you can barely hold onto them!)

Check your start/stop switch with your multimeter. My boat did not want to start on me at one point this season and it ended up being water worked its way into the switch. I took it apart and cleaned everything and coated all connections with dieletrical grease. It has been starting fine ever since I have done this.

However, if everything checks out ok, then most likely it is your starter. Replace it with a brand new one if that is the case or get it rebuilt.

I am going to take it to a local starter/alternator shop in town tomorrow and have them test it under a load and see what they get. I check the start stop switch and it did not have a bit of corrosion anywhere.

I have basically eliminated everything up to the starter..When I press the start button I get a click,which means the start button is working, along with the starter relay. When I jump the relay I get nothing which is why I went ahead and pulled the starter. Sometimes I gotta tap the starter with a wrench to get it to work when hooked up at a 12v source.

Sorry if I am repeating myself..its late.

Have you been hooking the 12v source right to the starter or to the starter cables?

alot of people over look cables. They wear out just like everything else, ive had to replace mine before.

but tapping on starter to get it over seems like the brushes are going bad correct?

or change batterys.. they can hold 12v but under a load go down real fast !

Power was hooked directly to the starter, and also through the cables to see if I could figure out if the cables were bad. The starter works sometimes, and other times doesnt. I will be purchasing a ebay starter this next week, or possibly buying oem so I dont have to worry about sealing it(even though that is easy to do)

I purchased a new starter from Electric Motor Service (800) 697-6070 for $170.00 FYI.
