this is meant for those iboats users who are familiar with parts counters at boat dealers. I bought a voltage rectifier/regulator for my Mariner 115 and noticed that on the counter a message said all returns will be charged a 20% restocking fee. Normally I wouldn't question this but once I got home I did a static check on the new part and the SCR and diode per the Seloc manual showed bad. The old part failed the Tach test as well as the SCR and diode, but by larger margins than the new part. If this part doesn't work and I need to have it replaced, should i expect to pay a restocking fee for a bad part. If that is the case, if I get 4 more bad ones I'll have to pay for 2 brand new ones to get one that works. Any thoughts on the subject. The dealer is Dixie Marine in Cincinatti. Hopefully the regulator will work fine and I won't have any problems.
