fullfuel01 Posted October 21, 2015 Share Posted October 21, 2015 I have 2 FIC module for Vmac1 engine. One got bad after alternator overcharged and burnt few light and truck stopped. FIC was bad..second is from a truck I got at an auction and they attented to jump start it on 24V to make it turn a little more faster. It was owned by a local guy and I knew it was running right before they did this. Anyone know what is this issue in in the FIC? or someone have a schematic of the interior?opened one and cant see whats wrong..

Dieselwrenches Posted October 30, 2015 Share Posted October 30, 2015 I would assume only Bosch had that info. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/42277-mack-bosch-fic-module/#findComment-309325 Share on other sites More sharing options...

41chevy Posted October 30, 2015 Share Posted October 30, 2015 Got it open and figured what was wrong it the box. I am a quick learner I guess. I personally would open it up and see if there is a Micro Fuse or a Fuse-able Link between the connector and board.

Mack log truck Posted December 27, 2017 Share Posted December 27, 2017 On 10/30/2015 at 9:27 AM, fullfuel01 said: Got it open and figured what was wrong it the box. I am a quick learner I guess. I have a 95 cl700 e7 that I have been having an intermittent engine shutdown issue. I borrowed a used fic module from mack and had the same problem. Took the truck back recently and they still are leaning toward the fic. They have no idea but think their module has the same issue as mine but as of yesterday they can not get my truck to run with mine but can get it to run with theirs, which I have never experienced that. @$2,800 for a new one im struggeling to take the gamble on buying a new one. Already have $3k into people trying to solve this problem.

Mike1 Posted August 6, 2023 Share Posted August 6, 2023 Did you ever figure out what was causing the truck shutting off . I have a1994 ch 613 em7 300 vmack 1 with very similar problems Quote Link to comment https://www.bigmacktrucks.com/topic/42277-mack-bosch-fic-module/#findComment-536404 Share on other sites More sharing options...
Joey Mack Posted August 7, 2023 Share Posted August 7, 2023 Mike1, that post is 5 years old. Check the engine grounds in front of the starter, and also, unplug the Duetch connector at the injection pump, and inspect for loose pins and cracked wires... You could, wiggle that plug while it's running to see if it cuts out and in, before you unplug it.. it should be secured in a yoke Quote Link to comment https://www.bigmacktrucks.com/topic/42277-mack-bosch-fic-module/#findComment-536421 Share on other sites More sharing options...

Someone jumped it with 24 V. I’ve pulled the fic out and I cannot see anything broke or burnt. What did you find on yours?
