Repairing Sealine LED Hour Counters

I cant offer much hope - from the pictures it looks like the wires go to the pins that come through the pcb once it is reassembled.

Also looks like there are only two wires being used positive and negative which I guess would just record the time that the ignition is switched on which would sort of go with my first comment.

Of course once you have cracked this you will become the forum expert who we will all turn to for advice.....
 
I don't think they are supposed to go back into the ribbon block (that's the controller for the old lcd).

If you look at the piccies, they are connected to the spiky "pins" in - whatever gets +12v when active.
 
have you got the right LCD ?

Thepipdoc, just before you start soldering, make sure you have the right LCD, if you ordered via the link on the other page you may have a counter and not an hour meter as I have. :(

The hour meter part number is 1856107. I have a 1856090 which is a counter

If you have the correct bit, you solder the positive wire between the P and I pins, and the negitive supply to N pin . these wires then go directly to the input terminals on the back of the meter, (by passing the ribbon ) see picture 13.

On the back of the guage where the plug fits there are 4 spade connectors marked S+ S- + - follow the connector through circuit board and from the picture it looks like the wires connect to + - . But I need to check this with Richard first.

Hope this helps, I've just ordered another LCD

Good luck

Bu**er!
I've got 4 counters, not hour meters!
On the plus side ( scuse the pun!)
Other people out there are either carrying out the same repair as me, or intending to do the repiar, so perhaps we'll solve this togever!
The mystery is:
Where do the wires go from the replacement LCD? Is it as Beeks said (Welcome to the forum by the way)

Also, given that I've got 4 counters and not hour meters would there be any benefit if I were to use one of the counters as a test device to see if it at least displays something, anything?
Surely if it displays a number then we can assume that it's wire correctly but just has the wrong type of display?
I want to try and get this sorted (all 4 of them) by this weekend because we're meant to be going to the Channel Islands, so if you get the impression that I'm in a hurry you'd be right!

If you have a volt meter, just check the plug which connects to back of the RPM guage, the 2 pins that have 12 volts to them with the ignition on, but without the engines running, are the pins that the wires from the LCD need to connect too. After all, all we doing here, is fitting a LCD inside the gauge and connecting it directly to a 12volt supply.

hope that helps

Interested to see how this goes as I have the same problem.

However if fitting an "hour meter" instead of the correct display to the original wiring it will only display the hours for which it has been powered. So you will need to leave it connected to 12V for the same time as your original hours to get the correct reading, this would be best done off the boat before fitting otherwise you will double the stored original figure ?

OK this is all starting to sink in!
I'm on the boat now, and with the ignition on I get 12.6v when I put a meter across the + and - wires, the ones with 2 wires going to the + and - terminals and not the terminals marked S+ and S-.
I now understand that what we/I am doing here is bypassing the existing hour meter and replacing it with a stand alone counter. ( yes you silly idiot I hear you saying!).

What I don't understand is this:

Doesn't this contradict the fact that it's a stand alone hour counter?
 
Yes, i was a bit confused by this as well.
You are removing the display from a knackd hour meter, and fitting an entirely new hour meter with integral display.

It will have no knowledge of previous hours run.
 
Ok I admit it - I'm confused.

By fitting the 'hour meter' from RS, will this start counting from zero or will the existing hours be stored and continue to count from where the old display left off? :confused:

The PDF link on page 1 seems to suggest that it restores the original hours but then again uses a different part.
 
I reckon we're fitting a completly stand alone hour counter that will start from zero and the numbers will increment by one providing it is connected to a12 volt supply.
The number of hours that would have been displayed had the LCD been functional will be stored somehwere other than the NEW LCD unit and the hours will continue to increase, but unless a brand new tachometr unit is fitted, the correct number of hours will not be known.
The bye-product of this whole repair procedure is that if the new LCD isn't allowed to run for the same number of hours that the original LCD would have displayed, the boat will have been "clocked".

I may well be wrong, but that's my understanding - I'll know for definite tomorrow night.

The RS LCD won't have any knowledge of the previous hours. But if you want match the hours to the another meter that is still working like mine or you know what the reading should be, you can leave a 12volts supply connected to the + - connectors on the back of the gauge for the allotted time.

Sorry to be so thick that I need to ask, but what is the difference between an hour meter and an hour counter?
 
It's not a hour counter it's just a counter. It counts how many times the power has been switched on and off. No good for what we what.
 
To find what the hours are/were you could try the old trick of putting the tacho in the airing cupboard (or perhaps sun?) for a day or so. Apparently that brings them back to life but not for very long but perhaps long enough to read them!
