Jul 21st, 2025 | | | | Joined: Jun 2009 Posts: 149 Wrench Fetcher | | Wrench Fetcher Joined: Jun 2009 Posts: 149 | I just had a few guage questions I need help clarifying, for 58 apache.
Fuel guage:
one post =hot wire
other post = wire to sending unit
Water temp:
Post one goes to hot wire
post two goes to unit on the block
Is that correct for those guages? Also, does it matter if the wires are spliced at all?
Last, the oil pressure guage. I put in a sbc motor that has an electric oil pressure unit. What is the best way to connect a sbc to the 58 mechanical guage cluster? All advice is appreciated! | | | | | Joined: Jul 2001 Posts: 3,887 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Jul 2001 Posts: 3,887 | yes on the first 2 - splices don't matter as long as you do them well, soldered is best ... the mechanical oil gauge hooks to a port just behind the distributor, small plastic or metal tubing kits available at FLAPS, same as used on aftermarket gauges

I just purchased a cheap electric water temp guage online, can I hook up my dash guage and aftermarket guage to same connection on the block? | | | | | Joined: Jul 2001 Posts: 3,887 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Jul 2001 Posts: 3,887 | I'd think not - they'll have different senders, but shouldn't be hard to find another place for the 2nd, there are thermostat housings that have'em

Hope I can jump in here....
My temp gauge is not working after the restoration.
I Switched out the sensor....still nothing. grounded the green wire to the battery...nothing from the gauge. Just want to make sure the wires to the guage are hooked up right..According to the after market wire diagram, the green wire (if I am sitting in the truck looking at the instrument panel) hooks to the left connector. The pink to the right. Now In the assembly manual for my 57 truck I can not find anything regarding if this is correct. I switched the green and pink at the gauge but still nothing. I am now thinking it might be the gauge. Which does not make sense as everthing is new in the dash. Could I have fried the gauge? I have power from pink wire to gauge and there is power at the sensor from the green wire. Does it make sense that the green wire has power down to the sensor?
Also, I tried to clean the threads in the head of the engine to make sure there was no paint in there.
All the gauges were working before I took it to the shop.
Would the grounding strap from the cab to the starter be a place to check?
Would the white resistor have anything to do with it?
Thanks!

If you don't like my carbon foot print, stick it up your Prius!! | | | | | Joined: Jul 2001 Posts: 3,887 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Jul 2001 Posts: 3,887 | power from ign sw to gauge is pink - green wire to sender is ground, varied by the sender, so yes you should get a voltage reading there from the terminal [green wire end] to engine ground ... with the wires reversed the guage would likely just read backwards .... when the key is turned on, the gauge should twitch up slightly from the left side [cold] - if you take the wire off the sender and touch it to ground the gauge should go to hot .... I'm not sure a ground anywhere would a problem .... not sure what white resistor you mean, but if that's the ignition resistor on the firewall, nothing to do with gauges .... short answer, if you have power to the sender [voltage reading from sender terminal to ground] it should be working, so suspect the gauge
you can check the sender [new one could be defective] with an ohmmeter, although I'm not sure what the particular values would be, resistance should change cold [high resistance?] to hot [low resistance?], best check would be off engine using flame or boiling water to see change
