My speedometer took a crap on me a couple days before the fateful ignition problems. So while I'm waiting for the new ignition part, I figured I would tear into the speedo cluster...

...Mikie gave me his speedo cluster from his old '90. I was going to remove the speedometer (electric) and modify it to fit my cluster (mechanical speedo). Also in the plans was to give Mikie his RR VSS in return for a Disco VSS (so he doesn't have to rewire under his crew cab :rolleyes: )

So far, this project has entailed:
- removing both speedos from the cluters
- removing the numbered face-plates
- modifying my old face plate to fit the newer speedometer
- modifying my old needle to fit the newer speedometer
- modifying the housing in the cluster to allow the deeper speedometer to enter through the back and meet up with the bezel in the front
- creating mounting plates to stabilize the otherwise loose speedometer floating around in the big hole in the back
- checking E-Bay and realizing there is a NOS mechanical speedometer for sale that would have dropped right in to this now goat-fawk of a speedometer cluster.

Dammit. The good news is despite all this headache, the cluster will look stock and I should be able to adjust/calibrate the speedometer to my current tire diameter and mis-matched speedo-drive gear (at the T-Case). The bad news is that Mike will have a hard time removing his returned RR VSS after I shove it up his @ss.

Too bad...so sad.

Already re-wired it to a second VSS I had. :D

But...I'll take it back anyway. Since you got it out and everything. Hehe.

Got that POS running yet? Me neither.

You need a speed sensor buffer if you plan to use the RRC VSS. The disco style has a better output with less trash in the signal then the earlier VSS. I would use the Disco style instead. The buffer may be in the speedo head, though.

But you never follow my advice you seem to enjoy struggling endlessly with electrical issues in true Lucas fashion. Oh yeah get rid of that relay between the ignition switch and you 'new' ignition system. It will cause you problems as feedback will try to keep the circuit live for a while.

Just say no to the prince of darkness

I still don't get why you want me to get rid of that damn relay...the only thing the ignition switch does is turn on the relay. Power for the ignition comes straight off the battery, through a fuse and goes through about 4 feet of wire.

So you would rather have me remove the relay, and rewire the igntion to the original igntion lead that covers about 20 feet of wiring and shares a fuse (read: primary circuit) with 15 other circuits in the car? If I did that, the voltage at the coil would be about 2 volts less that I've got now. Yeah, that's enough to trigger the ECU...

BTW Pendy, when you were shouting your anti-relay epithets earlier in my ignition plight, take comfort knowing that removing the relay from the circuit did absolutely NOTHING to solve the problem...


...why? Because it never has been part of the problem. Seriously, I don't know why you are harping on my relay. Next thing I know, the relay will be the source of the problems with my failed mechanical speedometer and the reason why my truck isn't on fire.

I'm digging Pendy's role in the daily soaps here on the LR forum - carry on! but there'd better be some hot babes on here pretty soon or it won't be worth watching anymore. someone has to get nailed or we kind of lose interest :flipoff2:

Should I bring back my old avatar?

You'll see when you finally get it running again. Maybe you should think about going distributorless!


Okay Mike get us something interesting to look at for your avator. How come noone is talking about The Behemoth being for sale.

Consider the pot stirred.

No one thinks I'm serious. Oh well, it's just fermenting for now...

:D
