I have a 2010 streetglide and have been back to the dealership 3 times for erratic readings on the oil pressure guage. First visit the oil sending unit was replaced, 2nd visit they said thay found a loose ground and 3rd visit they once again replaced oil sending unit. Guage will be reading 32 or so cruising at a steady speed then make erratic quick jumps anywhere from 0-32 sometimes sitting at 0 for a few seconds and back to 32. Has anyone seen or heard of this problem? Any suggestions?

 

your oil pressure switch has two pins on it . One controls the guage and the other controls the oil pressure light. If your light is not coming on, but the guage is acting erratic, I would guess the problem is in the wiring.

 

really seems that they should fix this on-going and consistant problem for good.

A loss of oil pressure will cause complete motor failure, which may result in injury or fatality if being operated.

A reliable gauge gives the operator ( any, not just the owner), notice of mechanical condition.

Use big words which allows the dealer to understand that this is a liability issue.

- and that you have records which show this is on-going and needs to be fixed, not just "parts replaced" hoping to solve the unknown problem.

Thanks, I'm heading to the dealership again today to speak to service manager and express my safety concerns!!!

 

Could be a bad gauge- these are not exactly 'made in USA' quality. I think my HD gauge was stamped Made in Taiwan or China.

 

New gauge on order. Hopefully I can put an end to this issue.

 

I had this issue with a Chevy truck I used to own. It was the sending unit.

 

It isn't the sending unit, did you read the OP?

Check your oil make sure it isn't low.

 

I had a similar problem with the Oil Temp gauge that I installed. It turns out the mechanic who did the fuel tank recall fix pinched the oil temp wires between the fuel tank spacer and the frame... I fixed that and the problem is gone.
