Re: I need HELP. *UPDATE*

I just reread you already have a schematic.

Re: I need HELP. *UPDATE*

You said that you have checked the fuses, including that one to the lower left of your 'circled' picture?

Re: I need HELP. *UPDATE*

Kesso,<br />Yes and I even replaced it with a brand new fuse just in case<br /><br />Where is the breaker? How do I switch it back on? I looked every where and still being a 2nd year novice I don't know were to look.

Re: I need HELP. *UPDATE*

Most Like Cable issues, corrosion etc. clean all connections. Next year take the battery out out of the boat. or at least disconnect it.

Re: I need HELP. *UPDATE*

nautiJohn,<br />After winterize I disconnected the battery, pulled it out of the boat and trickle charged it once a month trough the entire winter. Battery is fully charged

Re: I need HELP. *UPDATE*

I had a friend of mine who was working on it so I am not sure which cables he jumped on the starter and solenoid. When I turn the key there is no power anywhere in the boat and it doesn't click the starter either. He did a jump at the starter and got it to turn the motor a little. Then he jumped another wire and there was power back in the entire boat. Think it's the solenoid?

Re: I need HELP. *UPDATE*

DO you have any power at the front of the boat on the key switch? If there is nothing there I wouldn't suspect the solenoid yet.<br /><br />+12VDC goes from your battery to starter solenoid.<br />Then same wire terminal from starter solenoid goes to circuit breaker/fuse.<br />The other side of the breaker/fuse the wire goes to the alternator.<br />From the same alternator terminal it continues on to the multipin plug. It goes through that the multipin plug to the keyswitch.<br />(It also goes from the same terminal on the alternator to the main contact on the slave solenoid.)<br />The +12VDC comes from your key switch when in the start position back to the coil on the slave solenoid. This signal or +12VDC will energise the slave solenoid to enegize the starter solenoid.<br />Use step by step trouble shooting with a meter and you will find where the +12VDC stops.

Re: I need HELP. *UPDATE*

There is no power AT ALL to the front of the boat. When you turn the key......thats all it does is turn. Nothing else. Very details info thanks rattana. I need a lot of hand holding when it comes to electrical work.lol I am copying all the info I have been getting down but won't be able to try any until maybe Wed, or Thur. I appreciate everyones help. Thanks.

Re: I need HELP. *UPDATE*

lol, no problem. Lots of people have helped me out too. Let us know where there is no +12VDC when you test with a meter. See if you can get that boat running.

Re: I need HELP. *UPDATE*

I'll try tonight or tomorrow night after work. Thanks for your help.

Re: I need HELP. *UPDATE*

First of all I apoligize if you don't understand just what I am asking. I tried to make this as clear as I can. My set up doesn't look just like what is in the book so I think that is what may be confusing. Also don't laugh at the artwork. Thanks for any help.<br /><br />

 

[rattana]

Re: I need HELP. *UPDATE*

I don't know what that is, but it sure looks like it replaces the circuit breaker.<br />One of the other more experienced people on this board will know for sure.<br />You could set your meter to the OHMS scale and check the resistance between terminal A and B. It should be very low, like less than 2 or 3 ohms. If it reads a very high resistance then it is open, and blocking the voltage flow. I didn't see anything that looks like a reset button on the device.

Re: I need HELP. *UPDATE*

the block is a fuse but i have only seen it mounted to the trim pump to protect it<br /><br />your boat may have 2 ? how do the wires get to the trim pump most boats use 2 sets of cables <br /><br />i have never see a merc that did not have a circut breaker i have a 1995 3.0 and its mounted on the starboard rear of the engine were the cannon plug conects the harness its part of the orginal engine package i dont see how it cant be there<br /><br />tommays

 

[BigPoppaG]

Re: I need HELP. *UPDATE*

Thanks for the advice rattana.<br />Tommays,<br />do you have a pic of the fuse block for a Trim pump?<br />I will be taking a GOOD digital pic of the relay today or tomorrow. Hopefully someone can tell what this thing is. If I don't know what it is it's hard to replace or tell if that is the problem.

Re: I need HELP. *UPDATE*

Found out it is a 90Amp Fuse that Mercruiser used on some models. Gonna get a new one and see if it fixes the problem. Thought I did a pretty good job on the pic I made. <br /><br />

 

[tommays]

Re: I need HELP. *UPDATE*

the fuse should be easy to check without buying a new one eather it passes power or it doesent<br /><br /><br />you really need to stick with the basics of checking for power at each connection point and the condition of each one they may LOOK PERFECT but in fact will not pass power many times<br /><br />tommays

I HAVE POWER !!!!!!!!! <br />It was the fuse above. Tested the old one with the voltmeter......nothing. Got the new...tested it....got a beep...installed it and......<br /><br /> I HAVE POWER!!! <br /><br />Thanks guys for all your help.

Re: I need HELP. *UPDATE*

Good job on getting your boat running!!<br />The picture and the description was good too.

Re: I need HELP. *UPDATE*

Now you just have to find out why the old 1 blew so you don't have a repeat performance.
