jamies_wd21 Posted October 11, 2013 Share Posted October 11, 2013 Sorry, new to the forum. I'm interested in doing this mod as i have the same starting problem. My question is, are there 2 wires running to the solenoid? (#87 output, #86 Input) starter relay mod is pretty easy, you just need a standard 4 terminal relay from the auto parts store, ( 5 terminal can be used except you don't use one of the terminals),relay hooks up like this, the relay will have a number next to each terminal, this is where each number goes:#30 - 12 volts in - run a wire from positive battery to terminal #30 should use a fuse inline with this wire#87 - output of relay to what ever you want to turn on, in this case the starter solenoid, remove the wire from the starter solenoid, and in it's place run a wire from terminal #87 to the starter solenoid#86 - control current in ( turns the relay on) - extend the wire you removed from the solenoid and connect to this terminal (#86)#85 - ground, run a wire from this terminal to a ground, (I usually just loop a short wire from the terminal up to the mounting screw for the relay)That's the starter relay mod, basically when you turn the key to crank, power turns the relay on allowing power to flow from the relay to the solenoid, using this mod gives the power a shorter distance to travel to the solenoid.As I said I did this on my 94 and it lasted about a year before the starter finally crapped out, you have already replaced your starter, I have had no luck with reman starters and is why I just bought a brand new on from Rockauto.com and so far it is working perfect. It is possible the replacement starter you got is bad.almost forgot if you happen to get a 5 terminal relay the only difference will be it will have a terminal "87A", just don't use this one, the relay's with the 87A are known as change over relays, what they do is when the relay is off 87A has power/ 87 does not, when the relay is turned on 87A has no power but 87 does Link to comment Share on other sites More sharing options...
ahardb0dy Posted October 11, 2013 Share Posted October 11, 2013 no, on the relay, 30 is power in from the battery, 87 power out when relay is on to the solenoid 86 - from the switch ( old wire that went to the solenid) 85 ground basically you unplug the small wire that normally goes to the solenoid and connect it to 86 on the relay, than run wire from 87 to the solenoid Link to comment Share on other sites More sharing options...
