<VV> LM Gas Gauge Inaccuracy

[jvhroberts at aol.com]

 The HRPT has been a subject of much consternation! It's the horrid red plastic thingy that is in the engine compartment, and is used as a junction block for the main 12V feed to the rest of the car. The screw often loses its hold in the plastic, causing no starts, and a whole host of other electrical problems. I screwed in a brass stud with a nut soldered halfway in. Screwed this into the HRPT, and then stacked the terminals and held them with another nut and lockwasher. End of problems, even if the stud comes loose in the HRPT!

Thanks to everyone. I found the ground strap, snugged the screw. I'm not certain whether/how well it's connected at the ground lug on the instrument cluster. I like the idea of a dedicated ground wire from the lug to a good chassis ground. Even if it doesn't turn out to be the root cause of all my instrument evils, it's a smart move. I guess I need to pull the whole durn dash out and do that.




Dare the newbie ask what the horrid red plastic thingy is? Or will I need to brace myself with a vodka tonic first?

 That strap is a problem FAR more frequently than it should be. Worse than the horrid red plastic thingy. <G>



Add a dedicated ground wire, from the dash ground to the chassis ground, and never worry about it again! Make sure it's long enough to connect it with the dash in or out.

Where do I find the grounding strap at?











Jay,

 

There is a flat strip that is hard against the plastic backing of the dash  

that drops down from the back of the gauge cluster on the right side of the 

 steering column to the first bottom dash screw to the right of the 

steering  column (the screw points up and is one of the ones that secures the 

dash 

to the  dash frame).

 

Good luck.

 

Bob
