won't start replaced starter

yes I do even took wire brush to it to ensure clean conection

It should crank the engine in that case!!!.. Again.. NEW STARTER???

brand new , all I get are the lights. only will start when I bump it but start will not dissangage until I disconnect battery

Return starter!

ok starter checked out ok thou when tested should I try a different one

'IF' it is getting BATTERY VOLTAGE to the small wire at the solenoid when key is turned to START... Starter WILL engage!!! IF it's any good!!.. NOW, is it getting battery voltage at *small* wire when key is turned????
