yes it bothers me but I did find that with a test light I get the blinking coming out of the fuel gauge circuit board stud that travels to the temp harness pin. in fact I think I have 3 studs that are blinking and 2 others that are hot. I just may start at square one and us a volt meter on the...

thanks for everybody's great input. well today with the help of a service manual I traced the 2 wires ( oil pressure & water temp) thru the bulkhead (still blinking) up to the round connector that fits into the circuit board for gauges. the wires did blink as I tested them in the round...

yes mine do look like those but they are the original gauges. my after market gauges are both mechanical style. and work fine.

well I have after market gauges on my 68 barracuda and never tried to hook up these 2 gauges. amp and fuel gauge work fine. but the temp and oil pressure gauge will give a test light a blinking light when I connect the wire to the test light and the key on. if I leave the test light connected a...

hi folks well currently I just have a toggle switch with a fuse that runs from the fuse box and to the pump of course a ground back at the pump itself. been like this for 10 years just thought I would step up the wiring since I am going from a holley blue to a mallary 140 pump.

thanks for the input. i'll just give it a try and see what happens. what could go wrong with switching # 85 and 86 ?

Thank you this will work

does anyone know the wiring for a 5 wire relay? wire colors are black, red, white, yellow and blue. I currently just use a ground and hot wire/fuse for the pump. seems like I have seen one here but cannot locate it now. terry

well I returned the E3 plugs and went back to auto lite. will try the racing plug ar3923 and see how that works. otherwise the 3923 and 3924 seem to work good

ANYONE EVER USE THESE IN THERE SMALLBLOCK? I THOUGHT I WOULD TRY A SET IN MY 360/380 MAGNUM CRATE. SEEMS LIKE AUTOLITE WORKS WELL FOR ME BUT TOUGHT I WOULD GIVE THESE A TRY

ahhhhhhhhhhhhhhh now its clear as to the reason for the relay. i'll add one in when I change out the holley pump back to the Mallory 140. thanks for all your help and info

yes I do have the battery in the trunk and my pump is on the inside frame rail by the rear end. I do have a 7 amp fuse in line with the fuel pump hot wire but what is the added reason for the relay?

Thanks for all your input. once I looked at the volt meter I had it wired to the fuse box radio fuse. I changed the wire to my brake light fuse and now the volt gauge reads almost 13 volts at idle. I feel this is what it did read before this issue came up. I like the idea of a relay but I do...

thanks 67dart I do not have a relay connected to the pump. its been such a long time since I put in the volt gauge I will need to look and see what else may be on that circuit.

Hi folks what type of voltage draw should I see on my volt gauge when I turn on my electric fuel pump? my volt gauge will drop from about 12.5 volts to 11.5 volts. I have change fuel pumps from holley to a Mallory and I have change out the volt gauge for another. same draw. seems like my volt...

thanks for the input. i am tending to lean towards sg reply. the battery that i had in the car was in it for 5 years plus another 5 years in another car. well just last week i put a new battery in the barracuda because the old one would not stay charged if i left the dome light on for ten...

hi folks, i'm having a problem with my 68 barracuda that after about 15 minutes of driving i notice that my volt gauge starts to very slowly drop from about 13.8 to 12.8 volts.now i may go out tomorrow and it will start again at 13.8. any idea's as to what may be the culprit? terry

snake, on my 68 barracuda i did change the turn signal switch and found the orange wire went to a small light bulb next to the switch that was for the columm shift indecater terry

74, yes you can use the screws to mount the cap. i did this and felt it was a much better fit then the g.m style spring loaded clamps. if you don't have the correct screws just give msd a call and tell the tech person you need a set. they will get them off to you quickly (915) 857-5200 terry

hi bluefish very easy. first you will need a 4 post switch then battery positive cable to one of the large posts. cable going to starter on the second large post. a jumper wire roughly 10 gauge ( 3 inches long)from one small post to the large post of battery cable large post. and...

I Now Have Car Running Excellent. Turns Out The Pick Up In Distributor Was Bad. I Put In A New Msd Distributor And Wires That I Have Had And Bingo! Strong Spark! Thanks Everyone For Your Input It Did Help Terry

70bbdart, yes i am using a ballest resister and i am getting current to it. mod5v, i do agree its probly my pick up in the distributor.its not sending a signal to the msd box.when i test the msd box i do get spark then connect it to the distributor and no spark. i'll put in a new msd...

6pak yes i have tried 3 different coils with no luck.maybe an intermitent spark with one of them. i will just disconnnect the 6al and hook up the orange module and see what happens. terry

hi 6pak no i don't know anyone who has a msd6al.but i will now look. if i am not getting any spark out of the coil could this mean that my distributor could be bad or no my problem is before the distributor ? i do have a complete new msd distributor cap and wires, i can either go with...

i do have voltage running to the msd 6al. when i run the test in there trouble shooting instruction i do get a strong spark out of the coil. hense they say its hooked up correctly and should work i do have voltage at the ballest resister and coming out of the bulkhead. could a faulty voltage...

thanks mad i can try that, but if i am not getting a spark to go into the distributor cap from the coil shouldn't my problem lie before the distributor? thanks terry

ok folks update i bought a new coil from autozone and i thought i was getting a spark but it seems the longer i work on this i lose spark. did i go wrong with just getting a stock coil when i am running a moar performance distributor and a msd 6al ? now it seems that when i unplug the coil...

ouch! nothing worse then your issue. well seeing that you changed engines how about the grounding cables? one from engine to firewall one from engine to frame one from battery to block or head? good grd where voltage regulator mounts to firewall? any added electrical items like a...

thanks aarcuda, i will check that. but how would the gap change when its been fine for about 5 years now?
