I have a 1996 SPX and last summer I was having starter issues, which I fixed, but now this summer it was running good until me and a buddy were riding 2-up which is probably more weight than it should have on it but anyway we were riding and fell off a few times and the last time we fell off I jumped back on put the key in and there was nothing gauges didnt come on and no movement from the starter so I checked the battery the voltage is fine. my brother put power straight to the starter and it fired right up. then he talked to a mechanic and he said either your solenoid or computer control panel or something along those lines is shot, so he tried the solenoid, that wasn't it and was told whatever that computer control panel thing is that the mechanic was talkin about would be spendy. is there any suggestions out there on what to check, what it could be, or what to try? it would be greatly appreciated, thanks!
