May 8, 20187 yr Ok need my manuals, they are at home. Another thing check one of those good ones, but with the key in run position. If it stays good, that indicates that you don't have a flakey connection in that first level of circuitry. If the power goes away, you back track toward the battery.
May 9, 20187 yr Power goes to the ignition switch on a fat white wire. Power to the engine & ECU etc. is a Black wire. Should only be 12V when ignition is in run and start positions. It goes to the 3 fuses for: Meter Engine IG-COIL FUEL ECC Back Turn 4WD AT Those should all have 12V with the key in run & start positions.
May 12, 20187 yr Author Haven’t had a chance to look at her more, will be working on her all Tuesday hopefully I get a running
May 14, 20187 yr So the power at the fuses listed in post #25 is gone, as well as nothing in post #28?Have to start testing back toward the battery. Starting to sound like a corroded or broken connection.
May 14, 20187 yr Battery any good? I had a flat battery recently in one of our cars and it did some seriously weird stuff. The battery being flat was a result of a dead alternator... Cheers Bennie
May 19, 20187 yr Author This car is going to be the dearth of me. Now I have no power at the links but I got power at the wires going into the links from the bottom, still no power at any fuses ......anyone please HELPPPPP
May 19, 20187 yr That points to something at the fusible link box. Power has to go through the links to get to the fuse box. Careful inspection. All the connections need to be clean metal, no corrosion. The metal tabs can be removed. You want to check that the crimps are good also. I made a tool for removing the contacts from fuse blocks connectors, etc. From one of the stainless steel strips on the side of some windshield wiper blades. Depending on the particular connector, grind some width or thickness down so it fits - there is a plastic catch on the housing or a metal tab on the contact. Use the stainless steel strip to get into there and to release it.
May 20, 20187 yr Author I’m about to ready to junk this thing I hate electrical issues, thank for all your advice
May 20, 20187 yr Trying to run one of these old cars, you have to know or learn how to fix everything or have a load of cash to pay one of the rare places that will work on them. I'm guessing you are nowhere near Connecticut
May 20, 20187 yr Seems like you've got a place to start... And that's at least something. I'm hoping you checked those fusible links properly - they may be solid/not broken but they can still be dead. All the best with it. Don't give up! Cheers Bennie
May 21, 20187 yr Author I'm in colchester, pretty much the center of the state Yeah that’s about 1hr40mins from me. You work on these vintage gems? What’s your rate
May 21, 20187 yr I'm not a pro mechanic. But I have been maintaining and repairing my EA82s since 1988. Electronics engineer. I was designing and building electric and electronics since before high school.
May 21, 20187 yr Author I actually was testing the links wrong, I was tired retested them and they are all showing 12.5. Just nothing to the fuses key in or off
May 21, 20187 yr If power is not going from fusible links to fuse box then you need to check the wires/connectors in between. Disconnect battery and do a continuity check on the wires.
May 21, 20187 yr I actually was testing the links wrong, I was tired retested them and they are all showing 12.5. Just nothing to the fuses key in or off nothing to any fuses? or nothing to the ones that should get "key on" voltage? If the latter, the problem is at the ignition switch. If the former, the main wire to teh cabin.
May 21, 20187 yr Author No power to any fuses key in or out. I just changed the ignition relay thinking that was the problem but nothing, or at least that’s what I think I changed lol, it was brown and above the computer and still nothing
May 21, 20187 yr It's not a relay problem. Some of the fuses have power all the time. Some only when key is on run position. There is a relay for some other circuits also, but it doesn't matter if you don't have the always on and the switched power from the ignition switch. Anyone have scans of the schematic online?
May 23, 20187 yr Author Can the ignition switch cause no power in the fuses? I’m so lost when it comes to electrical it’s sad. Mechanical is my strong side
May 23, 20187 yr Some of the fuses are switched by the ignition switch. So, yes, if there were an open circuit between the always on feed to or from the ignition, switch, it could cause the switched fuses to never get power. The always powered ones are not effected by the ignition switch, the are fed directly from the fusible links. A wire could be broken inside, or a connection or crimp could be loose and corroded, causing the intermittent troubles.
May 24, 20187 yr id replace your fuseables just in case. i have had issues with other vehicles from faulty but not fully broken fuseables causing the cpu to fail safe and not power up. still had juice but it was intermittent weirdness and no start or even crank over. I doubt it will solve your problem but worth the $6 to me. keep the ones you pull in a baggy for emergency use. I'm certainly not the electrical person here, but have you unplugged the AC unit and bypassed the belt that drives it? if its fully locked up or otherwise faulty who knows what it is contributing to.
