Dirtyowlnumber4 Posted April 16, 2018 Report Share Posted April 16, 2018 driving on a dirt road in the middle of nowhere going around a corner at 5500 rpm, hit a bump back wheels went in the air mustve gone to 6200 or so and the coil lost all power i figure it must have something to do with this big bronze fuse by the battery, car doesn't sound broken sounds like it has compression just no spark anyway i might be able too fix it out here? all i have is a flathead screwdrivet Quote Link to comment

G-Duax Posted April 16, 2018 Report Share Posted April 16, 2018 Pulled the distributor cap off yet ? Quote Link to comment
banzai510(hainz) Posted April 16, 2018 Report Share Posted April 16, 2018 NO spark? how about ck the wires. see if something fell off. I always carry a mutimeter in my vehicle bronze fuse by battery? 1 Quote Link to comment
Stoffregen Motorsports Posted April 16, 2018 Report Share Posted April 16, 2018 Good call. In a collision, the first thing is always to check the dist rotor and cap. When jarred, they can contact each other and break one or both. 1 Quote Link to comment
G-Duax Posted April 16, 2018 Report Share Posted April 16, 2018 Check fuses, I've had them pop out. Check for push-on wires going to the coil & distributor. Check plug on ignition switch. Quote Link to comment
G-Duax Posted April 16, 2018 Report Share Posted April 16, 2018 I always carry a mutimeter in my vehicle I'd like to carry my whole shop & spare parts collection with me, but haven't figured out how. Quote Link to comment
Dirtyowlnumber4 Posted April 16, 2018 Author Report Share Posted April 16, 2018 nothing visibly broken in there. i noticed when it shut off that the tach dropped instantly when the engine died and didnt drop slowly with it, which makes me think power to it shut off. Quote Link to comment
Dirtyowlnumber4 Posted April 16, 2018 Author Report Share Posted April 16, 2018 Yah behind the battery is a black box inside are some wires and a bronze casing and inside that are two fiddly coils of fine red wire and some more fiddly bits. nothing visibly broken in there either though.

banzai510(hainz) Posted April 16, 2018 Report Share Posted April 16, 2018 GDuax I always carried a toolbox and Mutimeter(daily driver 521) cause I never had a cell fone. Got to learnon side of road Had a lashpad drop once but one needs tools to fix it. Most time it can be fixed right there its just finding the proplem ck the wires ,fuse box, battery hitting the hood cause of no tiedown(common Datsun owner trait) you pull the center wire and see if spark? ck for gas? Im not a A motor guy so Im just giving best guess 1 Quote Link to comment
Dirtyowlnumber4 Posted April 16, 2018 Author Report Share Posted April 16, 2018 no spark from coil. fuses all good. coil could have fried? ill probably call for a tow Quote Link to comment
G-Duax Posted April 16, 2018 Report Share Posted April 16, 2018 Doubt it was a coil failure. Still think something came apart on the wiring somewhere. I carry the essentials, electrical tape, duct tape, mechanical wire, some electrical wire, and a few tools. But it's illegal to carry what would cure an old car, a pound of C4..... 2 Quote Link to comment
Dirtyowlnumber4 Posted April 16, 2018 Author Report Share Posted April 16, 2018 could the ignition module fail Quote Link to comment
tr8er Posted April 16, 2018 Report Share Posted April 16, 2018 So you can crank the engine. Turns over. So starter good. Battery good. Engine not seized. Air isn't likely an issue. Fuel is likely okay based on how it shut off. Sounds electrical almost certainly. Sounds like the connections on the ballast resistor, starter, and dizzy, plugs need to be checked. Do dash lights still come on when key in? Ignition at minimum must work. Check the engine ground wire. That braided wire can get so beat up and corroded that a bump can break it. If that goes bad, the coil will have a hard time delivering a spark to the plugs. Quote Link to comment
Dolomite Posted April 16, 2018 Report Share Posted April 16, 2018 This is going to sound crazy, open up the dizzy cap and make sure the center contact on the cap is there, the one with the little spring. After a “spirited” run home from a buddies house that entailed air beneath all four tires, my 510 wouldn’t start. I went through everything and was about to give up when I checked the cap, the center electrode was missing...spring and all. I grabbed one out of my golf iii and put it in the 510 cap...fired right up and went to get a new cap. 3 Quote Link to comment
Dirtyowlnumber4 Posted April 16, 2018 Author Report Share Posted April 16, 2018 All right so i had my buddy tow me home 15 miles with a rope. First thing I tried when I got home was a new coil. no change. put old coil back on. fired right up. :/ This box seems to be ticking now. Quote Link to comment
Dirtyowlnumber4 Posted April 17, 2018 Author Report Share Posted April 17, 2018 All right looks like some of the wires have fried and harnesses melted but nothing else. The alternator is not charging the batt anymore either. Is this black wire wire the ground for the alternator? there is a wire down the line that fell off and looks the same. Quote Link to comment

banzai510(hainz) Posted April 17, 2018 Report Share Posted April 17, 2018 ck the batter ground for tightness also. weird this happen. Quote Link to comment
Dirtyowlnumber4 Posted April 17, 2018 Author Report Share Posted April 17, 2018 Wont start again today. same thing as before, no power from the coil. Checked and changed the coil and the cap, looked at all the spark plugs, disconnected the battery ground and cleaned it, but still nothing. All I have done since yesterday is ground the alternator because the battery wasn't charging. I'm thinking it has something to do with this bronze relay by the battery, it was clicking a lot yesterday. anyone know exactly what this is? Quote Link to comment
banzai510(hainz) Posted April 17, 2018 Report Share Posted April 17, 2018 is this a point or EI distributor? if POINTS then its grounding out. ck the points and screwes tight ect...... If a module then swap out a distributor. or module If not spark form the coil but is there power to the coil? 12volts to it? if not 12volts then its not the coil unless theres a big crack and shorted to groundhighly dought that) Quote Link to comment
Dirtyowlnumber4 Posted April 17, 2018 Author Report Share Posted April 17, 2018 It is ei. it is brand new maybe 50 miles on it only. I can get a new module. I tried 3 coils just now I know they all work. there are no volts to the coil. the power from the coil seems to come from this relay. it goes from the battery to the relay into the coil. I jiggled the relay around a little bit and now all electrics shut off when i try the starter. but i jiggled it again and the starter works again, just no power to the coil. Quote Link to comment
Dirtyowlnumber4 Posted April 17, 2018 Author Report Share Posted April 17, 2018 it looks fine on the inside though. Quote Link to comment
