mallory unilite problems !!!

[musclcar]

i'm having a hard time keeping the modules from shorting out and i've gone thru 3 of them in just one year maybe 1500 total miles. i've followed all the tips/tricks from century performance like adding power scrubbers and making sure all the grounds are good.

i was out driving my camaro today and started noticing my autometer shift-lite tach acting funny.the needle was really sensitive and was bouncing all over.also the back lite on the tach was flickering whenever the needle was not being accurate. i then noticed that my engine started to cut on/off like it did last year when the module died except i was able to nurse it home before it completely died.the funny thing is whenever i was idling there was no problems of the engine trying to shut off only when i was in gear and applying throttle did this happen to me.

i had to add a ballast inline from power source to keep power surges from frying mine, never had trouble after that. got the info from mallory tech support a couple of years ago.

that's what i'm using a mallory ballst resistor also all my grounds are either in 4 guage or 8 gauge.my battery is in the trunk so i'm grounded from the [-] side of the bat. to the r/rear frame then from the neg. side of the battery to the trunk bulkhead and both of those are #4 gauge wire. now the engine compartment i'm using an #8 gauge wire from the firewall to a bell housing bolt. all my grounds from the unilite and power scrubber go to the stock alternator bracket.now from there i'm again running a #4 gauge wire from there to the r/front frame rail.the ground picks up from there and then goes to the core support then finally to a fender bolt were the stock ground wire is located at.
