When I bought this boat last summer, it had the usual assorted problems a neglected boat has. One of the problems is that the warning alarm didn't work. It didn't work in the boat, or when I tried to connect it directly to voltage. I replaced it with the only 12v horn I could find from an auto parts store.
Now, the horn works fine when testing for high temp, but I get no initial beep when the key is turned on. I was told by an outboard mechanic that I have to use the exact horn supplied by OMC, but I find this a little hard to understand. It seems to me that the signal that the horn must operate on, is either a 12v or ground signal coming from the engine. If not, where does it come from?
I have the Johnson service manual for this engine, and it makes no mention of the horn beeping when the key is turned on. It only mentions 4 conditions that bring in the horn:
1) Overheat (I have tested this and it works)
2) No Oil (I removed the VRO as it didn't work, and now use premixed)
3) Low Oil (same as #2 above)
4) Fuel Restriction (not sure how to test this, as it only sounds at WOT)
I should also mention that I have the concealed side mount control, which has no alarm horn built in. Instead, my alarm horn is next to my tachometer on the main panel. This is on a 1989 Ranger boat.
Is it possible that I am looking for a beep when the ignition is turned on, and this type/year doesn't give a beep? I mean, it doesn't mention it in the service manual?
Hope someone can answer this for me. I know that my 1995 225 Ocean Runner did beep when the ignition was turned on, but this engine is 6 years older than that.
Thanks
