97 gtx electrical

[GONEIN67BIRD]

I got this ski a few years ago,always had a few gliches. Dess post bad changed that works good. fuel gauge doesn't read corrctly,12v low flashes on all the time,oil level low flashes on,speedo doesn't read correctly,the mechanical tach doesn't read but the digital one does. I am no mechanic but I find it hard to believe all these sensors have gone bad. Is there some part that could be messing up all these thing at once? Any advise would greatly appreciated.

Yea, with a 97 GTX is is quite possible.
Fuel gauge incorrect .... probably faulty fuel tank sending unit.
12 volt low .... probably needs voltage regulator/rectifier.
Low oil level flashing (normal) ... will start to flash if tank gets under 1/2 full.
Speedo inaccurate .... Paddle wheel in rear of ski probably broken.
Analog part of tach inop .... probably faulty gauge.

Sounds like a poor battery supply connection! Look for corrosion somewhere. From the battery terminals to connectors or even corrosion in the harness wires. Gonna need an ohm meter to check for continuity and resistance.
