by the way did not have this problem before l changed the altanater

Your solenoid is bad. Check your ground wire to the fender that grounds your battery, if it is not connected it can cause all kinds of problems. But the more likely cause is the solenoid and you need a new one.

sounds like your starter solinoid has a short . did you have this problem before you replaced the alternator?

You may have a fused battery wire or soleniod in starter or fender well type..

You did something wrong. Sounds like you melted the key switch into the on posision. If this is the case, you need to change the switch not the key. Most people think that where you put the key is where the switch is. This is not true, That is the key tumblers, not the switch.
Second That thing you call a magneto is a solonied. Not a magneto.
It is what engages the starter to start the car.

the ignition switch propably went out. it should be in the steering culumn. it might be stuck or loose. check it out
