It wont start unless I jump it

[dpuckett]

Mom's 92 recently had a bad ground (the little one in front of the battery that has a screw through it) burn out the starter relay, and took some wiring with it. Replaced the relay, redid the applicable wiring, moved the ground to a more secure location; worked fine for a week or two. The other day, it wouldnt start. I looked at it tonight, and the ground appeared good, but noticed the positive cable was loose at the battery. Tightened it up, figuring it is normally somethign simple, why would this time be any different? (Answer- Murphy and his danged law). Turned out to be the starter relay. At least when I jumped it with a wrench from the hot cable to the little stud/ nut on the solenoid, it started. Shut it off, key still on, hooked the test light in the little wire (brown, I think it is- runs along side the positive cable to the starter, where it branches off), and turned the key. Relay clicked, kinda, and no juice to the wire. Jumped the wire again, only this time it was the wire itself to the hot battery terminal, and it fired right over. Now I have figured out an emergency way to get it going if I need it in the future. However, I dont want to have to pop the hood every time to start the SOB. I was thinking (yup, that accounts for the smoke ) that if I just got a standard automotive relay for $5 vs $20 from DC, and rewired it to fit the new relay, this time with a wire crimper, solder (which I used this time round anyway) and the whole 10 yards, would that work, provided I got a relay of the same aperage rating? And what is the amp rating of the starter realy on a 92? There are 4 wires going to the realy, and 5 terminals on the relay, with an 87 and an 87A. ANy help or ideas would be greatly appreciated. Electrical stuff stumps me nearly every time, if it is beyond a loose connection or something blaringly obvious.
