Should I buy this bus?!? '74 Campmobile

[Tcash]

That rotor looks funny.
I would ohm test it.

Looks like some no name capacitor (condenser) as well.

Good luck

Both the condenser and rotor were bought from Napa when I did a refresh tuneup on the motor Before rebuilding. As suggested Tim, here are the multiple ohms of resistance of this brown rotor:

I'll be making a purchase of a Bosch rotor and condenser tonight.

Your readings are all over the place. Either the test leads are bad or the rotor is.
IIRC the resistance should be around 1 kohm.

Wall outlets read 117, just shy of the 120 volts. I can't believe the rotor is that wack. I can't remember what brand it was, but I'm usually happy and successful with Napa parts. Anyway, would my original coil be in question?
Condenser does indeed lack a maker mark, and has a red wire.

Edit: Both the condenser and rotor are Echlin products.

Ohm test the coil

So I noticed I can find Bosch ignition components on here in the classifieds as well as through various VW vendors. Locally I can acquire Beck/Arnley components, any grounds to think these would be worthwhile items?

I'll test the coil this afternoon. It's black but I haven't noticed if it's original VW or not, it sure as hell looks like it. From Ratwell's numbers, ohm levels between 7-9 are good?

Edit:
Picking up a Altrom Rotor from Napa today at noon. The Beck/Arnley stuff cost and special order status was enough for me to just buy a Bosch tube up kit from Bus Depot. I may check out Van Cafe.

Local Napa sourced a Altrom rotor from the warehouse, and when I picked it up I was pleasantly surprised to find a Bosch (made in Spain) rotor. First thing I noticed was the significant difference in weight and presumably quality between the correct and Echlin. $12.50 same day isn't bad.
Also noticed the bottom of the Bosch rotor has a 1.8 (my engine) and 983 (my canister short #), coincidence? I think not.

I tested the primary of the coil, reads 3.8 ohms. It is indeed a Bosch black coil stamped VW.

Just out of curiosity Ohm test the new rotor. Might want to right it down to.
Thanks

New Bosch rotor is good.
Took the bus for a little lap around town, too damn hot to be driving around for long periods at 100 degrees, but whoa was I surprised by the response on the throttle, the quick warmup, and the more consistent idle. I still need to tinker on the carbs.
I have a guy here locally with a true Brazilian ignition coil for $55 with a new bracket. I wasnt able to measure the secondary of the coil, any reasons why? I tried do as seen in the link Tim shared.

Interesting. So the implications of only the primary functions of the coil would allow power to the jets, chokes, etc but will cause what exactly to not function correctly? How could the secondary be bad and yet still fire up the distributor and allow the bus to run?

Tim, are you confusing yourself or us both?
The bus runs and has always ran with the known original black coil. Now is it possible for there to be some internal issue which allows for the coil to create spark but have a bad resistor inside or something?

Well maybe I have the Magical Coil
Or perhaps, just maybe I’m a doofus, but I like the first thought.
Still planning on going through with picking up the Brazilian coil tomorrow if the gent can locate it.

What’s a good wax compound to get that oxidation out, a month to the show and the bus needs to be nice..................

Yeah, apparently some guy in Arizona knew what he was doing
Thanks a lot Bill.

Center pin from Wolfburg West and Ate master brake cylinder from the classifieds on the way now. Hey, what's adventure without upfront costs? Right, okay maybe I'm beginning to justify the spending...

So both the WW center pin and Ate master cylinder are coming in tomorrow around lunch.
I have a couple questions. With regards to removing and replacing the original brake master cylinder, when going to install the new component, is it necessary to bench bleed the cylinder? I came across Colin’s techniques of bleeding the brake cylinder with it actually installed, loosely, and going through with the process of fitting the brake lines, again loosely, and priming the cylinder with the standard brake bleeding procedure.
Is this the best way to prime the master cylinder? Is there any other things to look out for or plan to do since I have the servo?
I hope this NOS Ate MC is as nice as the ole boy mentioned it to be, supposedly the seals are nice and soft.

Now for the center pin, I’m hoping it isn’t much more than what I’ve read on some very detail threads. It’s always a wonder when going into some nice and old metal sections with pivots and pressure. Better get some rest tonight and feeling mighty tomorrow afternoon.

Also have in the mail, a stock style Dansk muffler on its way, I can’t take the excessively hot and loud, let alone bulky twin-piped EMPI “performance” exhaust.
I’ve been thinking and lightly looking into the EGR valve layout and components on my 74. Please, wise and knowledgable folks, are there any perks to the EGR set being put back into the bus vs. leaving everything out? Apparently the 74 Cali-emissions layout is a little different than the years prior and the 75-79 layout?? The south, emissions are nothing of the matter, and two, the date makes it emissions exempt but I’m flirting with the idea of OG layouts.
Thanks guys
