My tach just started bouncing real bad at high rpm. I have a auto-meter silver-lite tach and a MSD-6al. Is it the tach or the ignition box??

I know this sound kinda odd but try using some electrical grease inside the boots on the plug wires. My old car did that until I tried the grease and it stopped and held the tach rock solid afterward.

If the spark plugs have several runs on them I would suggest at least changing the coil wire. That wire gets fired 7 times more than the other wires. The insulation starts breaking down & allows rf noise that the tach picks up as the engine firing.

Will it also read low at some times and correct @ others? also experiencing this, ready to dump all of the autometer crap out of my car if the SW were in stock with piss poor attitudes in customer service...?

COOK E , yours sounds like a bad connection. Is everything soldered or did you use a crimp connector?

 

[COOK E]

All crimp. Went through all the connections, ckd grounds. One time you can start car, and it seems to read normal, most others it reads any where from 1500 to 2200 low; looks like its reading but if you watching closely you can catch the jump up or down, doesn't really just bounce erratically
Talked with AM om Monday, they said will it was made by people who make mistakes so that I should send it back, and if I sent it out I should hear something within a week. The focker who I talked to Mon (who I never got his name) neglected to tell me they have a 3 week back log? WTF? After the last guy I talked to who I hope reads the YB, cause he will get his own thread soon.
I am ready to rip out the other 3 AM gauges out and replace them with some one Else's! His piss poor attitude about being over worked/under manned, will soon create a overmanned/ no work condition! How can or should they be that busy in the middle of race season? I could understand early in season or before season starts. Are the mfg. that much junk now a days? Whose Brand is a good alt choice over Auto Meter?

I have always had great luck with Auto Meter gauges. My new car has a Racepak UDX dash though and I would not change it for anything. As for them being busy , I would imagine this is a bad time of the year for them. Sorry for your misfortune. If you can swing it just buy another tach and save the other one that is being fixed for a back up piece.

the way Joes attitude I feel have no confidence that my tach will be working as it should when it does get fixed; and I will not by any thing new from autometer again. If they are that busy in repair dept, maybe they should look at improving the quality of what they are making.
Giving out response that "send it back, it was made by people and we mistakes"... that may be true and all, but it looks to me that there too many " close enough" tudes work there, or" o well" types; doesnt work with me. i work hard for my $$$ and will not throw it away on over priced sub standard pieces like my
Auto Meter 3965 - Auto Meter Sport-Comp Playback Tachometers that was like $275 when I bought it originally


BTW. earlier tonite I put an older sport comp tach in so i could run Sunday and guess what ... It worked like a tach is supposed to.

Thanks for the replies guys, I am going to try the grease first, it only does it at high rpm, it is fine down low. Also new plugs, new wires, just started doing it all of a sudden
thanks
Jim

Just an update, Marc Thank You. I put my tach in and ran last week, worked good, maybe a hudred or 2 low comparing it with the chips and shift selector but was consistant. I will keep Auto meter in mind the next time. Marc was very helpful in helping me with the problem after Joe was telling me it was my car that was the problem... marc replaced the module/board in mine, said tire shake was ususally the cause of problems like that and I was Like "oK?, tire shake in my turd?" when I re-installed the tach I found that the back of the housing was up against the bar on A pillar. thought that could simulate a shake always bouncing of that bar whether on track or in trailer. so I adjusted to a better posotion with almost a 1/2" of clearance!

Thank You
