Can anyone tell me what the trick is to get to the instrument cluster on my 70 Javelin? I believe the IVR is bad and I think it is behind the instruments but I can not figure out how to get to it.

Remove the screws from the dash overlay and take it off, you should see this:
There are four screws that hold the instrument cluster to the dash frame. Remove those and the cluster will be free other than the wiring and speedometer cable. You should be able to get to the regulator. You will need to remove the speedometer cable and wire bundle from the cluster if you want to turn it around. -Steve- Edited by Rebel Machine - Oct/20/2017 at 7:18am |

wow... that's one of my favorite dashes AM ever made... you seem like you need simple motivational encouragement; a man can go to the moon but he's gotta want to do it ya' know...
You might find this info encouraging, for inspirational purposes: Among it's other outstanding engineering features, '69/70 AMX was given the "Best Engineered Car of the Year" award for it's all one piece injection molded plastic dash which was 'an industry first' (truly) for the purpose of crash test safety. (The US Fed passed a law to encourage all car makers to eliminate steel framed dashes for safety starting in '67? & the '68 AMX-Jav dash was first of it's kind) so the plastic frame dash is evolutionary step between steel frame dash and air bag dash which came many years later... Anyway, all the big car magazines basically gave the '68 dash design a bad rating calling it 'bland and uninspired' blah blah blah (-I still think it looks great, it's a 'smart' dash and it's so dang easy to work on/very endearing) so for '70 (partly because the magazines complained) AM 'walked another mile' and gave the '70 models a restyled dash. So the '70 AMX-Javelin dash is 'AM's second all one piece injection molded dash'. It's styling is related to '70 Hornet all one piece injection molded plastic dash which is/was a historical milestone in automotive history for it's layout: the dash itself is a schematic diagram of the car itself. The Hornet dash is the same basic profile as it's original '66 Cavalier showcar which was a design exercise for styling symmetry. Anyone notice the profile of the '70 AMX-Jav dash subliminally alludes to the Go Pack roof spoiler? (where the Hornet dash is analogy of the car's profile?) (older brother '54 AM Metropolitan styling was based on 'NKI prototype' symmetrical design concepts and it's door skin stampings were/are interchangeable side to side) So with Cavalier based the symmetrical styled Hornet 'in the works', AM gave the '70 AMX-Jav a more symmetrical dash also... again tracing to '66 Cavalier but also contrasting the next incredible non-symmetrical styling features of the '71/4 Javelin. (aka 'the most highly styled interior of all time' for it's ~unique~ non-mirrored interior parts?) AM's '71/4 Jav has the most non-symmetrical interior of any car ever made? (the right and left sides are unique: not mirror images of one another) So this is the design significance of the '70 AMX-Jav dash; tracing to symmetrical Cavalier while contrasting non-symmetrical Javelin next year model. Something no one else ever mentions is how AM rediscovered the '70 AMX-Javelin dash styling for the '78 Concord-Gremlin/'79 Spirit-Concord models > again, linking those cars all the way back the '66 AMX Project IV models, where AMC History could be rewritten to explain how all 'pure AM' '66-up AMC styling can be traced back to '66 AMX Project IV styling exercises (including Pacer for it's extended application of non-symmetrical design ~in direct contrast to symmetrical Cavalier) ...could write a little book on it but I have no refined text to make a better presentation here at this time In essence, what I'm saying is, that cool dash in your car is very rich into automotive design history (in spite of apparent ...err, obvious... lack of astute observation) ...in my mind it's sort of like one of those 'love it or leave it' kinda things; hey man that dash is so cool! consider yourself a lucky man to have such a neat car! GO FOR IT! do-it-to-it! find some inspiration and make your AMC dream come true! '70 Javelin is arguably the best looking car AMC ever made IMO; excellent proportions from every angle ~beautiful car~ a true work of automotive art...

Even the voltage regulator in the dash is a historical item which relates to how US auto industry reacted to transition from 6 volt to 12 volt electrical systems.
Basically, the gauges were still constructed 'the old way' so the voltage regulator steps down the 14 surges of the 12 volt system to the 9 volt surges of the older 6 volt systems -same goes for the primary ignition circuit & why it has a 'resistor wire' leading to the coil Actually, the older 6 volt systems put out more amps ('electrical flow/volume') -to make the starter turn the older heavier rotating mass of the older engines... and the switch to 12 volts created more 'electrical pressure' to push through an increased amount of smaller wiring circuits, in order to reduce manufacturing costs; eg: a wire to the gas pedal is cheaper than an elaborate mechanical linkage... or wires to the windshield wiper parts are cheaper than the more elaborate vacuum operated systems before (but we lost the infinitely variable speed)... on the pro-side though wires are lighter than heavier mechanical linkage systems and that helps make newer cars get a better power to weight ratio... (in theory... until they put 50 more lbs. of copper wiring in there) so the simple fact your car has an instrument cluster 'voltage regulator' makes it historically significant in that regard, showing the car's position on the timeline of US automotive electrical system evolution |

Be wary when you attempt to remove that dash overlay.
It comes out a lot easier with the steering column dropped or removed. The overlay may be stuck up into the crash pad as well. You can reach up behind the dash and above the steering column with your left hand and find the speedometer cable and turn the nut loose and remove the cable before the instrument cluster moves, it comes out a lot easier that way. The seats are held in place by 6 fasteners each. Work on the dash is easier without the seats in place. |
