can any one help me figure this out? i am possibly going to be purchasing an Autometer fuel gauge, and the gentleman who is selling it says it reads 90 ohms when full. and 0 when empty. what i need to know is, what is the ohm resistance on a Honda sending unit when full/empty? will this gauge be compatible with the stock Honda sending unit? or shall i purchase one from Autometer?

 

Looked in the CRX manual troubleshooting:
Empty 105-110
1/2 25.5-39.5
Full 2-5

But may want confirmation from someone else.

 

wait it reads that many ohms when empty? i thought it was the other way around

 

Helms manual page 16-79 if you have access to one.

 

if you think about it ,more resistance=weaker signal,thats y the needle is down and up when u get less resistance...

 

ok so i got the gauge in with the wiring harness, which is the signal wire on the harness for the sender? i think i made a thread earlier about this particular question but cant seem to locate it.

 

 

lol i needed the exact opposite of that but thank you very much!
