Oil alarm. Mariner 135

Just finished fitting an early 90's Mariner 135hp 2 smoke to my boat. As far as I can tell all the wires are in the right place. When you turn the key the control box beeps a long beep then three shorter beeps then when the engine starts there's a constant beeping from the box. LOTS of smoke so oil's getting through . Oil tank on engine brimmed & getting oil from the remote tank under pressure, initially dropped as I fitted new pipes but cracked the top half a turn as it states on the tank sticker and oil comes out. Disconnected the wire from the cap sender (blue) plus tried disconnecting the wires from the oil pump unit no change and when the engine ran out of fuel (5 litres so no grass cutting now) the beeping continued until I turned the key to off.
Apart from the fact my 45 litre tank now looks a little on the small side what's my next move to silence the beep. Also rev counter hasn't moved. Is it possible the alarm has a short in the remote ? Engine & remote came as a unit.
Thanks in advance for any help.

Test your float to see if its your sensor also check the wires from cap to engine. Just had to fit a new one the wires had gone through right at top of cap. Also check that there isn't a crack in your black cap had that two years ago. Hope it helps.

From memory the 135 also have a sensor for the oil pump gear/ pump fails so if brakes the alarm will sound . Iv also had a few control units fails making the alarm sound constant due to the polarity on the battery

Do not remove cap disconnect both sensor leads from terminals connect ohmmeter between leads there should be no continuity through sensor if there is then the sensor is faulty replace full cap assembly.

Thanks for that Jambo & Yam man. It must be a more sophisticated system than I initially thought. The two wires coming from the cap, one runs directly to earth on the block.
What does the sequence of beeps signal when you first turn the key ? Is it some sort of system check & I'm struggling to understand why it continues when the engine runs out of petrol ?

The bleeps or flashing light is normal when starting but should stop once engine starts that's why I think your sensor is faulty. Do the checks. Another one is take your float assembly put and turn on your ignition and move the float up and down if there is no change in the bleeps your sensor is at fault. Get in the web and get yourself a manual for your engine Ivor a disc version on eBay.

No probs I had the values for testing the oil pump drive sensor / control unit ect ill see if I can dig um out. 1 warning tho if it is the control unit they ain't cheap. As I said iv changes quit a few due owners removing there battery's for winter and when sticking them back on they switching the polarity by accident .

Checked the cap and the battery polarity both fine ! The pump sensor seems to be my next stop. What has me beaten is the alarm continuing when the engine is stalled if it relies on a pulse ! Plenty of oil going in.

That's why I think it's your sensor assembly.

Sorry paddlers didn't explain my correctly , regarding the polarity I meant if by accident when connecting the battery you touched the wrong post with the cables . If you did have the polarity wired wrong at the battery you would more than a alarm fault ie fried engine harness .
