I don't have a 90s bike to know what that solenoid looks like (is it the same as on the 80s bikes?), but I can recommend general maintenance on electrical components. Get some electric degreaser and make sure all of the connections are clean and shiny since any crud in there can add resistance. Also make sure the connections are firm and snug, you may have to crimp them a little since any gap can lead to arcing which would melt the surrounding plastic. Also pick up a can of dielectric grease (it's usually right next to the can of electric degreaser) and squeeze some of that in the connectors. This keeps the water and dirt out of the contacts.
