A detailed spectroscopic analysis of SN 1986G has been performed. SN 1986G`bridges the gap' between normal and sub luminous type Ia supernova (SNe Ia).The abundance tomography technique is used to determine the abundancedistribution of the elements in the ejecta. SN 1986G was found to be a lowenergy Chandrasekhar mass explosion. Its kinetic energy was 70% of the standardW7 model (0.9x10$^{51}$erg). Oxygen dominates the ejecta from the outermostlayers down to $\sim$9000kms$^{-1}$ , intermediate mass elements (IME) dominatefrom $\sim$ 9000kms$^{-1}$ to $\sim$ 3500kms$^{-1}$ with Ni and Fe dominatingthe inner layers $<\sim$ 3500kms$^{-1}$. The final masses of the main elementsin the ejecta were found to be, O=0.33M, IME=0.69M, stable NSE=0.21M,$^{56}$Ni=0.14M. An upper limit of the carbon mass is set at C=0.02M. Thespectra of SN1986G consist of almost exclusively singly ionised species.SN1986G can be thought of as a low luminosity extension of the main populationof SN Ia, with a large deflagration phase that produced more IMEs than astandard SN Ia.
