ok, after getting my electric oil press guage hooked up to my d16, i found that it would not give out any reading. after all the trouble of making sure both ends of the tubing from block to sender didnt leak at all, the gauge needle wouldnt even move when i started up the car. i pulled the wiring out and just hooked it up straight to the battery and grounded it and it worked fine. so im positive that i just didnt hook up to a good 12v source.

usually i like hooking up electronics thru the fuse box so that if anything blow my stuff is still protected, but it seems of the several fuses i ran power from, none powered the gauge. is there any fuse that will work, or do i need a pure 12v source? if so, where should i tap from? thanks

ps: on a side note, i should use something one the ends of the fittings for safety rite? like teflon paste or something?

 

easiest=run wire from battery with inline fuse.

 

i hate having so many things runnin thru my firewall

which fuse would be safest to tap? or some other wire?

 

Since I do not smoke I used the lighter power and illumination for my gauges.

 

ah, i overlooked the mighty cig lighter! thanks, if i thought longer i prob wouldve picked that too. plus mine is close to where i wanna mount my gauge. i knew there was an accessory that i dont use that i overlooked....

thanks

anyone else is free for more suggestions if they think of something better

 

u wouldn't want to run it straight from the battery, that's a constant 12V and your gauge would be on all the time. Tap into your ignition/accesory power under the dash and run a 5amp fuse inline for protection from power spikes or shorts. Also, double check your ground. Hope this helps

 

I use the Cig ligter. It shuts off when the car is off.

 

 

fuse block has 5 spade connections, simple VOM will help you figure which are hotall the time, ignition controlled, and one that is hot when the parking lights are on. The last is helpful when wiring up the lighting circuits on the gauges.
