520H Improvements

Recommended Posts

As stated on a previous post my oil pressure light keeps flashing regardless of everything I have tried. Rather than being worried about the actual oil pressure I elected to install an actual gauge along with also a hydro temperature gauge. Quite a bit of work but worth it.

Oil pressure is actually much higher than expected with 25 at 1500 RPM going to about 59 at full throttle.

Having a bit of an issue with the hydro temperature sensor. Was working fine but suddenly no reading. Will replace that shortly.

What is your source for the gauges?

Got them off Amazon. Only drawback is temperature gauge is Celsius, however just found a similar one in Fahrenheit.

 Their supplier must be coming from maybe Canada? We are still in Fahrenheit and I am old school and that's the way it will stay!  Nice looking gauges!

I am having the same problem, and would love to do the same thing. What exactly did you do? Forgive me, I'm still new to small engine work... But pretty good at rigging things up.

Its really simple. Just a bit labor intensive due to the difficulty in removing the engine shroud on the Onan. Once that is removed you just need to remove the old sending unit above filter and replace it with the one that comes with gauge. The new one is substantially wider than old one and would not  thread in correctly since it interferes with filter housing , so a two inch nipple was necessary to extend it past that point. Then its just a matter of placing a wire from it to  the gauge. The second wire in the old one (blue I believe) just needs to be grounded so hour meter works when key is turned. Then the gauge itself needs to be grounded (black wire) and red wire connected to power source activated by switch. I merely tapped it into the 15AMP fuse which is switched that way.

The temperature gauge very simple also. Merely replace sending unit with new one and use same wire. Find the wire in back of dash (dark green) and tap into it to gauge. The other two wires same as the other gauge.

I am not a fan of the dummy lights and the oil pressure one was worrying me. This way there are no questions whether there is pressure or not. One can foresee a problem before its too late, from both the oil pressure and hydro temperature.

Searched high and low and could not find a digital Fahrenheit one for the 2" pod. Sure enough when I am done I find one. Going to change it. I don't want to be doing calculations while I am driving it..
