Remote starter hookup

[wjob]

Where are the correct connection points to hook a remote start button back at the engine on a1988 150hp suzuki? Wiring diagram shows a hot, light weight yellow/green wire that energizes relay starter so assume that connection at relay would be one point, however that connection on the relay seems to be a sodered joint with a black wire which I assume is a ground? Then that black wire runs for about one inch and is then sodered to the relay body?

What are the correct two connection points?

thanks

OK -- I read this again. Thought you wanted a button on the dash but I see you want it at the engine. I won't ask why. Wire it the same way I just described. The +12V can come from the large terminal on the solenoid that has the positive battery cable on it. The other wire connects to the small terminal I described earlier.

Re: Remote starter hookup

The remote switch has two terminals on it. Connect one to a +12V source. Run the other one back to the starter solenoid (start terminal). The starter solenoid has two large terminals and one or two small ones. One large terminal has the positive battery cable on it. The other large terminal has a large cable on it that goes to the starter. If the solenoid has only one small terminal, thats where the start switch wire gets connected. If the solenoid has two small terminals, the second one connects to the engine block (ground). Is the regular ignition switch shot?

Re: Remote starter hookup

Thanks Silvertip. I understood your explanation and have hooked a remote up many times on OMC's and inboards as you described but that's my question. There is no starter solenoid back at the engine, only a Starter Motor Relay and the Starter Motor. As I said, according to the manual wiring diagram, it appears that the yellow/green wire coming from the ignition (I believe) going to the Starter Motor Relay would be one of the hookup points but there is no way to do it at the relay, as I explained. I tried hooking into that wire before it gets to the relay, where a bullet connector is used to connect the lead from the dash to the lead from the relay but because of shrink wrap on that connector that's a no go unless I re-do that bullet connector?

Hope you follow all this. Will await your reply

Re: Remote starter hookup

So where does the positive battery cable connect? If it connects to the relay -- that's the same as a solenoid. It's possible the solenoid is part of the starter. If the positive battery cable connects there, there should be a small wire there (possibly originating at the starter relay). In effect, all you need to do is connect the switch the same way the normal start switch is. Splice into the wires by cutting them. Put heat shrink tubing over the wires. Solder them and cover the joint with heat shrink.

Re: Remote starter hookup

The heavy positive battery cable comes into one side of the relay, then there is another heavy + one that comes out of the relay and goes to the starter. Only other wire going to starter is the heavy minus (ground) cable from the battery.

The light, positive yellow/green wire that I referred to looks like it's coming from dash ignition (hard to trace in diagram) and going to the relay, which along with a light ground wire, I'm assuming excites (closes) the heavy relay contacts sending battery voltage to the starter. Problem is that on the relay itself it looks like the yellow/green wire is actually soldered to the ground wire on the outside of the relay case. Doesn't make any sense that the hot yellow/green would be soldered to the ground wire?

I'm not trying to hook up a permanent start button back at the engine but I like to be able to clip on one of those portable push button starters in the event I'm by myself and I need to start back at the engine. Based strictly on the wiring diagram, it would say clip on to the yellow/green (the only light wire coming to either the relay or the starter) and the heavy hot lead at the starter but I don't want to do that if in fact the yellow/green is soldered to the ground?

On other engines I've never had to clip on to two of the heavy hot leads such as the one coming into the relay from the battery and the heavy + connection at the starter (from the relay)?

Appreciate your thoughts

Re: Remote starter hookup

OK - that relay IS the starter solenoid. Relays and solenoids do the same thing. They use a low current coil to energize a set of contacts that can carry a large amount of current. Clip one lead of your button to the yellow/green wire which is the HOT (ignition) side of the relay. Connect the other lead from the switch to the POS battery cable. When you push the button you send 12 Volts to the relay coil. The relay energizes which connects the two large terminals which sends high current to the starter.

Re: Remote starter hookup

Thanks Silvertip!

So, I guess you are assuming that what appears to be a soldered connection between the yellow/green and a ground wire on the outside of the relay case, really isn't? If it were and I clipped on as you have suggested, I'd have some real fireworks? On the other hand if the yellow/green did not connect to ground on the outside of the case, but rather went to the + end of the low current coil inside the relay unit, then your explanation would seem correct.

Your comments please?

Re: Remote starter hookup

Since I can't see the soldered connection between the yellow/green wire and what you think is a ground wire I, like you am confused. If what they are calling a relay has a metal case, use an ohmmeter to see if its grounded. The relay coil (low current) should only have +12V in, and the other end must be ground. That's either the case or a separate wire. We know what the large terminals are. I have a drawing of how to make a solenoid jump switch. I'll photobucket it and post it in a couple minutes. Just consider the solenoid in my picture as your start relay.

Thanks Silvertip. Appreciate all your help.

Have any thoughts on my overheat questions in thread, "'88 Suzuki 150hp Overheating"?
