Starter motor relay crack

So in the process of everything else I came across this lovely crack in the relay for the starter. Now when the bike was parked less than a month ago everything was (seemed) fine with the starting system, think I need to replace it?

After some fiddling this is what ended up being my scenario.

Now I know that the wire broke (trigger wire I think) and I'm sure I can figure that out. but how about the now missing piece of plastic?

Think I can fill it in with some gorilla glue or similar product? unless someone else has some suggestions?
 
That one will work. Just wire in a bullet or a spade.
Just make sure it's 12 volts.
 
I was doing a search to figure out what is wrong with my starter motor and discovered this old thread. Bike is a 1983 750E. Starter would not work. Put a screw driver across and it fired right up. So I assume I need a solenoid ? Found one at CT. My question is, what do I do with the 4th wire. I see the 2 connections at the top, but only 1 spade on the bottom. Though it does say it is 4 pole in the description. Is this one a good choice ? $17 versus $59 from Boulevard.

If it has three visible terminals (as in your picture), it is probably grounded through the mounting bolts.

If it has four terminals, one is for the trigger, the other one needs to be grounded.

Some vehicles use a switched "hot" wire for the trigger, others use a switched "ground" wire. The four-terminal solenoid can handle either one.

Our bikes use a switched "hot" wire, so the three-terminal unit will work just fine.

So do I just leave the extra wire { ground } hanging ? Or ground it somewhere. Excuse my electrical ignorance.
 
if your relay has a fourth wire i think you will need to ground it.

Notice in the above diagram that a relay uses an electromagnet. This is a device consisting of a coil of wire wrapped around an iron core. When electricity is applied to the coil of wire it becomes magnetic, hence the term electromagnet. The A B and C terminals are an SPDT switch controlled by the electromagnet. When electricity is applied to V1 and V2, the electromagnet acts upon the SPDT switch so that the B and C terminals are connected. When the electricity is disconnected, then the A and C terminals are connected. It is important to note that the electromagnet is magnetically linked to the switch but the two are NOT linked electrically.

You must ground the 4th wire. One of the mounting bolts should work nicely.
