Hello, before I yank my alternator and take it to some box auto parts store to be tested, here is the scenario
My battery is only charging at 12.7 when running at increased RPM. The battery is good and will hold a charge. I am getting "same as battery" voltage at the alternator stud (high 12s)...
So, I've been chasing my 14.95 overcharging battery on my 72 RR. Here are my voltage drops testing from battery positive
Red wire connector at Molex (engine side, closer to bulkhead) .16
Blue wire at Molex (engine side) .21
Ignition switch (probing blue and red wires on switch side of Molex) .12...
I am running a couple of glass fuse taps to power my aftermarket gauge/tach, and I want to make sure I haven't bypassed the fuses. Which side of the fuse should the taps go to make sure I don't have an unprotected circuit? (Fuse box is internet photo, but same one I have). Thanks
I have been chasing an overcharge on my 72 340 RR for a while. Got lots of help from you guys but I'm now officially stumped.
I was charging at 15.5 at idle and had 1.50 voltage drop from battery positive to blue alternator wire. I got it down to 14.95 and 0.9 drop after cleaning and going...
I have been chasing this overcharge for a while, and you guys have helped keep me pointed in right direction. Thank you. But I'm still too high, and electronics is definitely my weak link so please bear with me. 72 340 RR
I'm charging at about 15.25V. I get 1.5 voltage drop from battery + to...
My battery is charging at 15.3 to 15.6 depending on rpms. I am a newbie to electronics and some of you guys are brilliant. I need help. I did research on site and ran some tests. I unhooked the field wires at the alternator and battery did not charge (I believe that means alternator is good). I...
What is going on? I wanted to fine-tune my timing on my 340. It was originally at 17 initial, 35 total (don't run vacuum advance). I looked for highest vacuum and idle. When I was done, it was right back at 17/35. This is where it gets strange. All of a sudden, I had hot start issues (never...
When you adjust a vacuum advance canister, are you adjusting the amount of timing it puts in the engine OR the amount of vacuum needed to accuate the advance?
Four people have told me one way, three the other.
If it matters, it's a JEGS Mopar Electronic ignition distributor on a 340. Thanks
I just installed a Retrosound stereo in my 72 RR. All is good. Fit and sounds real nice (thanks to Jerry Landes in Texas for his 4×10 front adapter)! My question is I have been in the habit of always disconnecting my battery terminal when car is idle for days or weeks (or when I work on anything...
I'm a relative newbie, so forgive this question. When I use a push button remote bump starter, where do I hook the two alligator clips? The instructions are a bit fuzzy.
One goes to positive battery (or maybe the large battery post on the starter relay) and the other goes to the ignition post or...
I just installed a mini starter in my 340 (after pulling engine for winter refreshening) and it grinded teeth for a second when I first tried to start it.
The second time I turned motor over, it fired right up.
When I started it again two days later. Same thing. Grinded first time I turned it...
I feel stupid for asking this, but I am getting ready to start rebuilt 340 and want to make sure it fires right away.
I've ready many posts on this -- and I think I know the answer -- but want to double check.
I want to install distributor at 20 degrees advanced (to facilitate a quick start and...
Does anyone know where to find this correct sized bullet connector? The two standard sizes don't fit. .156 is too small, .188 is too big. I believe Mopar OE is .185. I thought I could get a .188 in there, but no go. Anyone know where to get correct size -- or a not-too-complicated place to get...
Simple question but one I'm not sure about. Does the "Batt" male terminal at the bottom of fuse box supply constant power (as I suspect) or is it Ign 12V switch power? I know Accessory side is 12V ignition but I'm already using that side. I'm looking for 12V Ign switch power for an aftermarket...
The timing mark on my 340 just started bouncing when I try to check total timing. It holds perfect at 18* at idle but when I get to about 2500-3000 rpm it bounces so far, the timing mark goes out of view. Any suggestions? I recently put in a light spring in distributor in exchange for heavy...
Pardon my ignorance, but If I'm checking for current on the violet wire at the driver's side kick panel or at the tail light, does the engine need to be running with car in reverse or is ignition On with shifter in reverse good? Thanks.
So, here is my issue. I removed the rallye dash on my 72 RR to work on speedo. Put everything back in place and now the temp and fuel gauges don't work. I grounded both at the senders and turned key and they didn't budge. 20 amp fuse for gauges is good, I'm getting 12 volts at tan wire out of...
I just pulled gauge cluster on my 72 RR rallye dash (thanks for help) to work on speedo. Everything went pretty smoothly but now the left side dash lights aren't working. Everything on right including parking brake light and turn signal work but nothing on left. It's definitely not the bulbs or...
