Does anyone put a fuse the tach wire?

Does anyone here put a fuse on the tach wire? I've learn from an older installer that didn't put a fuse on the tach wire so I never did, but recently I came across an installer that did. I didn't think it was a bad idea at first to have a bit of added safty on to your work. So, on most of my recent install I've began installing a fuse on the tach wire. This week one came back when the fuse holder broke. The first thing that I check was the fuse on the tach wire because it was something new that I've added to my recent install. I never have any problems and complains from my customer with the Autostart Starter product and my work, so I kinda knew it was link to the fuse that I've recently began installing on the tach wire. When I was testing to find out why the remote starter was not starting I can hear the starter craking and the engine seems to be on at the same time, so I hit the brake after a few second to stop the remote start. I had the customer standing beside me and I didn't want to them to think I screw up the install on their car. I quickly cut the fuse away and join back the tach wire the way I have done many times and the car just started up beautifully. The customer was happy and I was relief. The customer was in and out in less than 15 minute, but in the back of my mind I don't feel very good at all because I got about 25 cars out there that's got a fuse on the tach wire. I am worry if the fuse break or the fuse holder break sometime down the road the starter will continue to crank during the remote start period since there is no reading on the tach wire to tell the remote starter to disengage the starter. I am worry about damaging the customers starter motor. Before I start calling my customer back to get the tach wire rewire I thought I get a second opionion from you guys.     I need you guys to give me a bit of reasurrance here. The starter product that I used is Autostart. One of the feature that it has is "Starter anti-grind" I hope this is the feature that stops the starter from cranking when a tach signal is not detected. Is that what "Starter anti-grind" mean? Let me know if that's not correct.      There is an old adage in the saying if the method that you been using works, you should stick with it. I think I am going to go back to my old method for now.     Be careful whose advice you buy, but be patient with those who supply it.

no on the fuse, and as for the anit grind, it prevents the vehicles starter from engaging when the vehicle is already running hence the term ANTI GRIND.  to see if it works, remote start the vehicle and put the key in, turn it to the crank position.  it shouldnt do anything.

i would not worry about the cars taht you did fuse ,all i can say is that i dont use fuses but i will tell you that the tach wire you install should never see ground so make sure when you run them they are not able to be shorted! If a tach wire is grounded it can make the car run like crap and verry unstable driving conditions. The fuse does not seem like a bad idea but you dont need it. I dont even know if the fuse would blow properly if it was shorted since you are dealing with a alternating current circuit that is changing polarity a bunch of times per second and this wire will never read the same voltage due to reving engine and all so dont use fuses at all and dont worry bout the cars u did!

I've been doing remote starts for about two years or so, and I've never put a fuse on a tach wire. I really don't see myself doing it in the future either.~The Rookie~
