96 Polaris magnum 425 4×4 starting trouble

hey guys, ive searched over the forums and cant seem to find the answer to my problem. so i bought a used 96 polaris on craigslist. i got it starting up good and than i was riding around the backyard and she just shut off. wouldnt start back up so we gave it a jump and now it wont turn over on her own. the start button worked last time i got it started. Now the only way i can get it to start up and turn over is the old screw driver trick were you touch both the solenodes. i have a clymber manual and it seems to be hooked up right. we have one red wire off the battery on its own solenode terminal and the other terminal has the red starter wire and the red/white wire coming from the starter. so basically my question is what problem does the screw driver hack fix? that is i guess were the weak link in my system is.
P.s. is there any good stickies on the brakes for these? came with no working brakes so im working on getting that going.
thanks guys!
