RED, BLUE & GREEN ELECTRONIC MODULEs of the '1979 UNIFLITE ALARM, 7 POINT W/DUAL HELM OPTION'

[Kevin McIntosh]

Hey all ... does anyone know anything about the location and nature of the alarm electronic modules?

As referenced in Uniflite Owners Manual wiring diagram '1979 UNIFLITE ALARM, 7 POINT W/DUAL HELM OPTION':

Thanks, Kevin Mc

OK, I believe I've located the RED, BLUE & GREEN ELECTRONIC MODULEs associated with the alarm system ... as shown on the wiring diagram above ... they are attached inside the flybridge f/g moulding, on center (FYI - there was a clear, plastic cover installed over what is shown below):

 ... the clear, plastic cover contained a substantial amount of powdered, blue-ish, oxidated copper ... and the remnants of at least one RECTIFIER DIODE ...

I was a little surprised to find that the ELECTRONIC MODULEs were nothing more than a set of RECTIFIER DIODES soldered to the rear side of the (PIN?) half of three 6-position connectors ... that connect to three 6-position (SOCKET?) halves of three bundled wiring looms that enter the back of the tan coloured plastic housing base from the Stbd. side.

Unfortunately, the modules assembly was positioned on center directly below an opening for the Forward navigation mast light in the flybridge f/g moulding ... the mast / base / wiring was likely disturbed at some point in time for servicing (or ?) and the opening in the f/g moulding for same not resealed properly ... dried, whitish, saltwater residue can clearly be seen where water has run down onto the top of the electronics modules' housing base and clear plastic cover (otherwise probably meant to protect the modules from errant physical contact) ... the housing / cover was never sealed against this water intrusion eventuality and the cover appears to have collected and partially filled with water, eventually destroying the exposed (solid?) copper wires interconnecting the rectifier diodes of each of the modules.

This no doubt explains the presence of a directly-adjacent, disconnected, 9-position Yellow connector (8 positions utilized, so far, I'm having trouble identifying this connector on either available wiring diagram):

1 Yellow

2 Green

3 Blue

4 Violet

5 Yellow

6 Green

7 Blue

8 Violet

9 (empty)

It likely also explains the wire connector (a 9-position Blue connector, 7 positions utilized) found disconnected under the lower helm console, discussed by me in this thread, which I will now close.

So, now I am going to have to try to figure out how to re-construct the electronics modules myself ... all I need are some more details beyond what I see in my alarm wiring diagram and / or some rationalization of what the rectifier diodes were intended to accomplish ... the electrical rationalization is, at this point, beyond my knowledge, however, I am capable of the solder work required to re-make the modules ... what I need is a technical inventory of the diodes (their values / identifiers) and a detailed schematic of how they interconnect, for each module (unless it is as simple and straightforward as what is shown above in my Uniflite alarm wiring diagram) ... perhaps a tall order at this point in time I know, however, you don't know 'til you try.

Thanks for any insights offered, Kevin Mc

I have the wiring diagram for the alarm systems shows where each wire from RED,BLUE,GREEN electronic modules go.If that would help let me know and will figure a way to get it to you

GP / Maggie Harbour ... thanks for stepping up and helping out ... is your wiring diagram different from the one I posted above (502400-5, REV A, DRAWN 7-21-78 by HUBKA)?

If so, yes, I would appreciate the opportunity to review it.

mine is from feb 1975 ill post and you can review

hope you can read?

Hey GP ... thank you so much!!!

Your alarm wiring diagram appears to be of slightly different issue / version (1975 issue vs. 1979 issue no doubt ...  are you able to read the author's name, date and / or version number of your drawing on the lower right ... where the Uniflite, Inc. box is?  if so, may I ask what that info is?), and, with respect to my focus on the alarm electronic modules under the f/b enclosure (have you physically observed yours there?  what is their condition? [make sure they're not exposed to any water running down from any Fwd mast light, as mine were] if they look better than mine, a close-up, hi-res pic of them would be extremely helpful to me), is essentially identical to mine ... the drawn Gray wire routings on the left towards the three ELECTRONIC MODULES differ slightly on yours, as does the positioning (on the diagram) and circuitry of your 'ALARM BELL's: Gray & Pink wire connections vs. my: RED ELECTRONIC MODULE ->>- 6R6 -< 6R2 <- #20 Orange/Black -< 6R2 <- Gray 'AUDIO UNIT's wiring connections ... however, as far as my desire to re-construct these modules is concerned, I think our alarm systems are pretty much identical.

Thanks again GP, Kevin Mc

I have an older system for the alarm. My boat is a 73 42sf  twin cummins 555. hope this helps

Hey GP ... thanks for the additional scan and photos ... so, if I understand correctly, you have a '73 42' Convertible (SF) with a 5 point alarm system (4 engine warning lights [port Oil & Water, stbd. Oil & Water], a Bilge Water high light but no Drive Oil warning lights [high temperature / low oil pressure, depending on gears model] ... your diagrams' 'Auxilliary Alarm System Diesel' is roughly equivalent to my 'Dual Helm Option', that repeats the 7 warning light panel on my f/b) ... and ... you have a Uniflite 7 point alarm system diagram drawn February 25, 1975 that (is for unspecified model types / lengths / year, although presumably the '75 model year) more closely resembles my own 7 point alarm system and diagram ...

Your diagram corroborates what my diagram shows ... however, I will still need to identify the rectifier diodes by type(s), value(s) and technical (part #) descriptor(s) if I am to reconstruct the electronic modules ... short of that, I will need to carefully remove my electronic modules and attempt to forensically identify exactly what was used ... I'm hoping the situation is as simple as the diagrams make it out to be ... that all the rectifier diodes are are of the same type / value ... that, to me, seems doable.

Thanks again for stepping up, sharing your images and further helping me out GP, Kevin Mc

That's correct! my ser# 115   I got owners manual from secure tech long ago must have put in schematics they had? I have B/W Velvet Drive Transmissions. twin disk had alarms. this drawing is from 1971. Hope you can read.

Hey GP ... thanks for the additional photo ... unfortunately, when I zoom in, the resolution of  that photo suffers and I can't really read it all that well ...

 ... if the drawing is from 1971, perhaps I probably shouldn't rely on it too much ... but thanks just the same anyways ... Kevin Mc
