Hey all,

I have yet another questions about starters.
I have narrowed it down to a faulty safety switch, which works about 90% of the time. What happens is that the motor will not turn over. I have replaced contacts, so I know its not that. Tried a new starter, and it wouldn't turn over at all (it was Nippondenso aftermarket brand). I measured voltage to battery pos. terminal on starter and its getting a full 12V. The safety however, is only drawing 7V. It should be 12 also.

I decided to make a jumper from the safety switch terminal on the starter to the battery + terminal on the starter. As most of you have guessed, as soon as the battery was connected, the starter motor ran continuously. Not a good thing. I only let it run for about 3 seconds! <img src=http://www.ezboard.com/intl/aenglish/images/emoticons/embarassed.gif ALT=":o">

So my question is, I am guessing my jumper should be from the safety switch connector to the battery + terminal on the starter, and bypass the safety terminal on the starter all together. Does this sound correct?

I am getting tired of chasing this gremlin down. I could really use some help here on how to bypass this switch.

To bypass the switch all you need to do is tie a wire across the switch contacts. This will short it out and defeat the swich.

Are you sure it is the switch and not a wire problem to or from the switch?

Geln,

Where are the switch contacts at?
All I have is a one wire connecter to fasten to a spade terminal on the starter.

I am not 100% sure it is a switch, but since it isn't pulling the voltage across during starting, I can only presume that the safety switch is going bad.

I don't know what kind of car you have. Even so, I doubt it it the safety switch, but it could be the problem. To prove it, you should be able to start it up in neutral, if it is the switch. I would check the fuselinks for a loose connnection to start with if the neutral trick doesn't work.
